roll crusher with stable performance | fote machinery

Applied materials: coal, pebble, limestone, dolomite, granite, construction waste, pebbles, glass, cement clinker, basalt, iron ore, quartz stone, coal gangue, etc. Its advantages: high capacity, ability to handle wet, sticky feeds.

Roll crusher, as one of the most economical and practical crushers, is designed to handle the first and second crushing of friable minerals and stones such as coal, clay, coal gangue, limestone, slag, cement clinkers, and shale, etc.

According to the number of rollers, the FTM roll crushers can be divided into three types: single roll crusher, double-roll crusher, and multi-roll crusher. And the most common one is double-roll crusher.

Roll crusher is applied more widely than other crushers because of its small volume and cheap price. With the adjustable discharging system, it can be used flexibly in coarse and fine crushing processes of the industries such as cement, chemical engineering, electricity, mining, metallurgy, building materials, and others.

Roll crushers can adjust the wedge device between rollers to control the feed and discharge size of the machine. Also, it is equipped with a spring device to protect the crushing machine and avoid shutdown caused by overload and iron passing.

When the adjustable bolt pulls the wedge upward, the wedge pushes the movable roller away from the fixed wheel, then the gap between the two rollers becomes larger, and the discharge port becomes larger, and vice versa.

The gasket device adjusts the size of the discharge by increasing or decreasing the thickness of the gasket. When the gasket is added, the gap between the two rollers becomes larger, and vice versa.

The unique structure of rollers makes selective crushing of the roll crushing equipment. Since minerals fed are crushed along its internal friable crack, the finished products are uniform with the cube shape.

The minerals are crushed under the force of rollers and machine body, and ores smaller than the gap between roller and machine frame (of single roll crusher) or roller (of multi-roll crusher) will pass directly without repeated crushing.

With the supporting CPU, operators can control roll crushing machines and monitor gaps between rollers, and clean up the crushing cavity through the central control room, which will help save energy of 30% to 50%.

The main working parts of the roller crusher is the cylindrical rollers. The rollers are supported by the fixed and movable bearings, and they are relatively rotating which are driven by the motor. The materials are crushed by the friction of the rotating rollers, and the finished products are discharged from the gap of the rollers.

The spring is used to balance the pressure generated between the rolls. If there are non-crushed materials falling between the two rollers, the compression spring of bearings can be pushed to make a large gap so that non-crushed materials can be discharged immediately.

The quality of the crushers has a great impact on its price. The high-quality equipment will cost more in terms of workmanship, technology, materials, etc. Meanwhile, it will have a long service life, low failure rate, and better performance, and bring more profit to investors.

In 2019, Fote has exported a total of 39 roll crushers to India, Indonesia, Zimbabwe, Vietnam, South Africa, the United States, Pakistan, the Philippines and other countries, mainly for coal, bentonite, rare earth ore, limestone, aluminum, manganese and others.

river sand making crusher

At the same characteristics of the ore itself will influence the production play a role, as in the case of the same concentration as well as other river sand making crusher, the density is smaller, the greater the viscosity of the slurry to produce a product will be more coarse granularity, for high density minerals, sand to increase the concentration of reduced and vice versa.

When we in the actual operation, to improvise according to actual condition, keep up with the demand of the market change, make the river sand making machine more environmental protection, more energy efficient, more attention to the details of master production at the same time, it can help us better for production.

We all know that appear river sand making crusher greatly solve the problem of insufficient supply of natural sand, sand excavation of a large number of broken only lead to serious ecological balance, but also seriously affect the supply of construction materials, at this critical stage, river sand making crusher have come into being, sand is sand production line not missing equipment, sand making machine manufacturers want to take certain measures to make the appropriate improvements to machinery and equipment, which makes its production efficiency can be improved, making their own for more more economic benefits.

We carried on the comprehensive analysis for river sand making crusher, found that many factors that influence system sand machine production, but play a key restriction factor for these main aspects: ore properties, equipment structure and operation method, pulp (concentration, feed quantity, uniform degree), etc.

artificial sand - what is it and how to make it | fote machinery

Artificial sand, also called crushed sand or mechanical sand (m sand), refers to rocks, mine tailings or industrial waste granules with a particle size of less than 4.75 mm. It is processed by mechanical crushing and sieving.

In China, the artificial sand was mainly used in the construction of hydropower systems. For example, the Three Gorges Project and the Yellow River Xiaolangdi Project used artificial sand to prepare concrete. Due to the remote environment of the hydropower project and the high quality of sand and gravel, the projects have taken the materials locally.

Many Indian states have decreed the use of crushed sand in infrastructure construction because of its high compressive strength and cohesion and the adverse environmental effects of river sand mining, which will greatly boost the demand for artificial sand.

There are both natural and human factors in the increasing demand for artificial sand. The former is that the natural sand is about to run out, while human factors include people's requirements for environmental protection and the need for high-quality concrete.

With the development of infrastructure, the natural sand resources formed by hundreds of thousands of years in many countries and regions have been almost exhausted, which has affected the further development of construction projects.

Driven by huge interests, natural sand has been indiscriminately mining, which changes the river course, affects the safety of river embankments, destroys the living environment of fish and contaminates the groundwater. The crushed stone sand is an important alternative resource to change this phenomenon.

In the process of mining river sand, it often produces a large amount of tailings which is not used reasonably. Especially in small mines, the tailings are piled up at random, occupying land and polluting the environment.

Besides, in urban planning and construction, a large amount of construction waste is generated, which actually can be crushed by the crushers to produce the artificial sand and aggregates for promoting resource utilization.

With the rapid development of concrete technology, the comprehensive performance of high-performance concrete and high-strength structural concrete has higher requirements on the quality of aggregates, requiring it with stable quality, good gradation and shape, while less and less natural sand meets the requirements. Therefore, people are turning their focus on artificial sand.

Artificial sand and mixed sand are mainly used in building construction, municipal construction, transportation, and other projects whose concrete strength grade is below C60. When meeting the corresponding technical requirements, they can also be used for concrete projects such as ports and water conservancy.

The vibrating feeder feeds the stone evenly into the coarse crushing machines for the primary crushing of the stone. The crushed stone from the coarse crushing equipment is transported through the belt conveyor to the fine crushing machines for the secondary crushing.

The primary crushing equipment directly processes supplied materials from the stone material factory and is the foremost processing plant. The jaw crusher is the ideal choice for primary crushing.

The secondary crushing equipment is responsible for the middle and fine crushing in the stone crushing process. The secondary crushing equipment mainly includes impact crushers and cone crushers.

The crushed material is conveyed by the belt conveyor to the crushed sand making machine for fine crushing. The finely crushed material is then screened through the vibrating screen for coarse sand, medium sand, fine sand and other specifications.

VSI sand making machine is called high cost-effective sand making equipment with low initial investment cost and good use effect. It is high in operation efficiency with the PLST crushing cavity.

The HVI sand making machine manufactured by Fote is more advanced in technology. Its butt ends and lubrication scheme are modular in design, and the peripheral guard plate can be turned up and down to extend its life cycle. It has the effects of sand making and shaping at the same time.

For those with strict requirements on the powder content of sand, a sand washing machine can be installed behind the sand manufacturing machine, and the sewage discharged from the sand washing machine can be recycled by the fine sand recovery plant.

The following video shows clearly the difference between crushed sand and river sand from the aspects of source, wastage, setting time, shape, silt content and so on. It is worth collecting and sharing with friends.

The table below shows the mix ratio of M15 M55 and M55 M55 concrete designed for artificial sand and river sand. The results show that in the same Concrete Mix Design, the strength of concrete by artificial sand is higher.

As the demand for aggregates from China, Africa, Latin America, Europe,etc. will continue to rise, and the price of artificial sand will also increase, the outlook for the global aggregate market for sand and gravel is worth looking forward to.

According to the Global Sandstone Aggregate report, by 2020, the demand for aggregates of sand and gravel in the Asia-Pacific region will increase the fastest in the world, and the growth rate of India, Vietnam, Malaysia, Indonesia and other regions will be among the best.

Due to the economic transformation, the demand for sand and gravel aggregates in China will slow down. However, the report predicts that by 2020, China will still be the world's largest aggregate demander, accounting for almost half of the world's total aggregate.

The Global Sandstone Aggregate report shows that the reserves of natural sand are gradually decreasing globally, and in some developing countries where the demand for aggregates and sand is huge, illegal sand mining has happened frequently. According to the report, by 2020, the reserves of natural sand resources in some countries will be quickly depleted.

The depletion of natural sand resources will lead to a sharp increase in the price of aggregates and artificial sand, especially in areas where the demand for aggregates is huge. It can be seen that the profit margin of the artificial sand is very large.

The m sand manufacturing machine produced by the supplier Fote is suitable for m sand making production line of high hard and abrasion-resistant materials such as limestone, quartz stone, granite, river pebble, basalt, cement, various ores, glass raw materials, mechanism building stone, gold slag, etc.

The limestone, widely distributed in nature, is easy to obtain. It is the main raw material for manufacturing cement, lime and calcium carbide. After being processed, limestone is used in large quantities as building materials. Generally, simple processing process is through the limestone sand production line.

Quartz is a hard, wear-resistant, chemically stable silicate mineral mainly composed of silicon dioxide. It is an important industrial mineral raw material generally used in glass, building materials, ceramics, high-tech electronics industry, etc. after crushing and sand making.

The granite has the characteristics of hard texture, high strength, abrasion resistance and weathering resistance. It has the title of "The King of Rocks" and is a good building material. It is rich in resources with low mining costs but high product value. Granite is a popular choice when the product needs to be weather-resistant or durable.

The river pebble resources are rich with low collection costs and high application value. After making sand from river pebble, it is widely used in water conservancy and hydropower, expressways, high-speed railways, passenger dedicated lines, bridges, airport runways, municipal engineering and high-rise buildings in the engineering field.

Basalt is the best material used for repairing roads, railways and airport runways. With the characteristics of strong compressive resistance, low crushing value and strong corrosion-resistance, it is the best cornerstone for the development of railway transport and road transport.

Doyou want to turn construction waste into treasure? Doyou want to crushlimestone, river pebble, granite, basalt, and quartz stone into small particle?Do you want to get economic benefits from these stones?Then it is high timethat youchoose a jaw crusher! As a matter of fact, it is widely used to crush ore and large pieces of material in mining smelting, building material, road, railway, water conservancy and chemical industry. Brcauseit has so many applications, it is also called universal crusher.

The jaw crusher plant, which is researched and designed by Aimix Group, has combined with domestic and foreign advanced technology. Our crushers adopt deep crushing cavity, so the feeding rate and crushing efficiency can be greatly improved. It is also energy-saving. Compared with other crusher,it can save more than 50% energy. Jaw crushing plant has advanced technology, long service life, reliable working condition, easy maintenance and other advantages.

As a leader of mining machinery, this kind of crusher can process almost all the rocks and minerals, such as: basalt, pebble, iron ore, limestone, granite, quartz stone, shale, gravel, river pebble, bluestone, gypsum, construction waste, building aggregates, etc. In other words, it can turns all types of stones into useful materials.

Firstly, You should consider the size of raw materials and the required size of the finished materials. If the materials have big size, you can choose the ordinary crusher machine(PE series). Because itis the primary crushing equipment and suitable for crushing large stone materials. On the contrary, you should choose Aimixs secondary jaw crusher or other kind of fine crusher machines in order to crush smaller materials.

Secondly, you should consider the machines performance. Aimix, a reliable crusher supplier, adopts advanced technology to manufacture all kinds of crushers. Accordingly, our crushers have simple structure, easy maintenance, stable performance and low operation cost. So you can choose our crusher machines without hesitation.

Lastly, jaw crusher price is a very crucial factor. In addition, we can recommend suitable machines to different customers according to their budgets and requirements. We ensure that all customers will get best crusher with the most reasonable price.

On the basis of actual situation, the most popular types are PE series, PEX series and HD Germany series. Each type contains several models. For example, PE series mainly contains 18 models. The smallest model is PE 150*250, and the biggest machine is PE 1600*2100. PEX series mainly consists of 5 models. Besides, HD series is a kind of German version crusher. Aimix mainly manufactures and exports 4 models of HD crusher- HD80, HD98, HD110, HD125.

The main specifications of this kind of crusher machinesare PE series crushers, PEX series crushers and HD series crushers. PE crushers are mainly used in primary crushing stage. However, PEX crushers mainly work in secondary or third crushing stage.

PEcrusheris the most common kind of crusher machine.It consists ofPE150*250, PE250*450, PE1200*1500, and so on. In orderto satisfy different demands, thecrusher havea large range of inputsize and outputsize. You can adjust the size according to the requirements of theraw material and thefinished product. The inputsizes are from 125mm to 1020mm. Moreover, each type of inputsize can be adjusted from 10mm to 300mm.For example, the large input size of PE150*250is 125mm, and you can adjust the input size from 10mm to 40mm based on 125mm. The things you need to do are putting the materials into the crushers and adjusting the size you want.

PEX series mainly consists of five models: PEX 150*750, PEX 250*750, PEX 250*1000, PEX 250*1200, and PEX 300*1300. Besides, HD Germany crushers are also a main type of concrete jaw crusher for sale. And there are four types of HD crushers. They are mainly used to crusher hard materials. Compared to other crushers, it has larger production and higher quality finished products.

There are several main parts of jaw crusher: frame, jaw plate and side guard plate, and transmission part. The frame is a four-walled rigid frame, and it is used to hold the eccentric shaft and stand the reactive force of crushed material. So, the frame needs sufficient strength and rigidity. It is usually made of cast steel. The frame of mini jaw crusher for sale can be made of high quality cast iron instead of cast steel. The frame ofthe crushrneeds to be cast in sections and bolted firmly into a whole, and the casting process is complicated. The frame of self-made small jaw crushmachinecan be welded with thick steel plate, but the stiffness is poor.

Both the fixed jaw plate and the mobile jaw plate are composed of jaw beds and jaw plates. The jaw plates are fixed on the jaw bed with bolts and wedge screws. Jaw bed of fixed jaw plate is the front wall of the frame. Jaw bed of mobile crusher jaw plate must have sufficient strength and stiffness to stand the broken reactive force, and thus most mobile jaw plates are made of cast steel or cast iron pieces.

The eccentric shaft is the main shaft of the crusher, which is made of high carbon steel. The eccentric parts must be precision-machined and heat-treated. One end of the eccentric shaft is a pulley, and the other end is a flywheel.

When the rock crushing machine works, motor drives belt and pulley, and the eccentric shaft drives the mobile jaw plate. When the mobile jaw plate rises, the angle between elbow plate and mobile jaw plate becomes larger. So the mobile jaw plate will be close to the fixed jaw plate. At the same time, materials can be crushed. When the mobile jaw plate down, the angle between elbow plate and the movable jaw becomes small. And under the effect of rod and spring, the mobile jaw plate will be far from the fixed jaw plate. Meanwhile, broken material will be discharged.

Crushing chamber (working chamber) is composed of a fixed jaw plate and a mobile jaw plate. The mobile jaw plate is periodically reciprocated against the fixed jaw plate, sometimes separated, and sometimes closed. When they are separated, the material enters the crushing chamber and the finished product is discharged from the lower part. When they are closed, the material between the two jaw plates is crushed by crushing, bending and splitting.

2. This kind of crushercan not only crush small size materials, but also crush large pieces of limestone. And the largest broken particle size is 1000 * 1200mm. In current mining industry, limestone is in short supply and many ordinary crushers can not crush large size limestone. And itcan crush large limestone into small particles, so you can get more crushed limestone by using ourcrusher.

However, different jaw crusher manufacturers have different prices. So we suggest that you buy crusher machinefrom professional manufacturers. Aimix Group, a professional crusher exporter, can produce all kinds of crushers, such as hydraulic crusher, no grinding crusher, impactor crusher, direct drive crusher, double chamber crusher, cone crusher machine, and track mounted jaw crusher.

pe series jaw crusher for primary crushing | hxjq

There are many particle size reduction devices including jaw crushers, impact crushers, cone crushers, and hammer crushers, among which jaw crusher, as the longest and most popular crushing equipment, has been widely used in the primary crushing of materials.

Jaw crusher is the traditional crushing equipment with many models and large output. PE jaw crusher is mainly used for primary crushing of various ores and undisturbed materials, also used for both coarse and fine crushing.

There are many models of PE jaw crushers, among which the most popular models arePE-7501060, PE-600900, PE-150250, etc. In order to meet the strict requirements of customers, the crusher has been extended to the PEX jaw crusher under the constant innovation of engineers, which is also known as the fine crusher.

This crusher has been widely used in mining, building materials, roads, railways, water conservancy, and chemical industries, as well as crushing various soft and hard ores with a compressive strength of 350MPa and a diameter of 500-1800 mm, such as river pebble, granite, basalt and other metal ores. The PE jaw crusher has a significant crushing efficiency with a large crushing ratio and a high output, which is favored by the majority of users.

This crusher is used in almost all minerals and mining industries. Whether dealing with metal ore or non-metallic ore, we can offer you a solution that reduces the size, for a series of our products are available for crushing, downsizing, beneficiation with reliable design and versatility for your application. PE jaw crusher can process 1-2,000 tons of ore per hour, so in Africa, many gold mines choose our Jaw Crusher as the primary crushing of their entire beneficiation line.

In September last year, Mr. Brighton from Zimbabwe found us and consulted us about the mineral processing equipment that he needed equipment that could process 10 tons of gold ore per hour whose feed size was 200 mm and discharge size was 7-30 mm.

According to the project information he provided, our technical manager designed a complete production line for him, including jaw crusher, cone crusher, ball mill, spiral classifier, flotation machine, and dryer. In this situation, a jaw crusher must be used for primary crushing in order to achieve the required discharge size, granularity, and higher quality end product.

As a result, the technical manager proposed a PE-250400 jaw crusher for Mr. Brighton to meet his requirements for incoming and outgoing materials. This type of jaw crusher can reduce 5-21 tons of ore per hour which is suitable for his requirements now, even the future when he wants to expand the production. Compared with raw gold ore, the gold ore processed by the mineral processing equipment is more expensive and more versatile in the world, and also more attractive to the customers for higher profits it brings.

Many infrastructure industries have a solid foundation, which is a variety of rock aggregates. Recognizing that the widespread use of these aggregates has prompted us to continuously create and improve our rock crushing equipment to help boost your production, reduce maintenance times and increase overall operational efficiency.

Aggregates that are crushed from large stones are essential raw materials in construction, transportation, and other infrastructure construction. Therefore, the role of crushing equipment in the aggregate crushing production line is critical.

Our PE jaw crusher is commonly used throughout the industry to reduce the pieces into the required sizes and to impart fineness to the broken material with high quality and efficiency. It can make rocks, sandstones, river pebbles, and other materials into various granularity that meet the requirements of construction sand with high compressive strength, being more in line with building requirements, and characteristic of improving building quality.

In June 2018, a construction company from Ethiopia found our promoters, because they were about to carry out the road construction project and hoped to crush the basalt raw materials (250 mm to 500 mm) into the sizes of 00, 01, 02, 03 (00 stands For fine below 4 mm the dust; 01 between 4 mm to 8 mm; 02 stands for 20 mm; 03 stands for 20 mm to 32 mm.), and due to the large amount of work, it is necessary to crush 200 tons of basalt per hour.

Based on customer's information, we had customized basalt crushing solutions for customers, including jaw crusher, cone crusher, sand washer and circular vibrating screen, among which, the PE-7501060 jaw crusher model can meet all the requirements of customers, which means that the crushed basalt had a uniform particle size and was very suitable for road construction.

PE jaw crusher is widely used in coal mine operations and attractive to customers because of its uniform end granularity, lower noise, less dust, and less pollution. Under strict environmental regulations, a good deal of coal mine projects has been suspended due to large pollution, which has seriously hindered the development of mining plants, resulting in low efficiency in major mining areas.

However, we have actively responded to the call for environmental protection by using advanced technologies and new materials to manufacture this crusher to meet national environmental standards. Coupled with PE's superior discharge size and simple operation characteristics, our company has been chosen by many users.

The rapid development of society has led to the production of many construction wastes. The original construction waste is not treated, not only occupies the land, but also causes pollution of rivers. The application of the crusher not only solves environmental pollution but also brings a high economic benefit for investors by recycling the construction waste into valuable materials.

The brand is shaped by innovation. This new generation of jaw crushers has redefined itself with advanced technical design, which can improve material flow and production in quarrying, mining, demolition and recycling applications, and for which this machine has become a deal solution for large manufacturers and crushing operators.

This crusher adopts the most advanced crushing technology and digital component processing equipment to make the internal structure precise, thus there is no dead zone in the deep cavity crushing, which could avoid blockage effectively, improving the production efficiency.

Continuous collaboration with laboratories enables state-of-the-art technological innovations in the durability of wear parts and the reliability of mechanical components, extending the service life of the whole set of equipment, among which, the movable plate is made of high-speed steel castings, and the eccentric shaft is processed by forging blanks, which makes the equipment more reliable, efficient and durable.

The PE series jaw crusher can be driven by a diesel generator and an electric motor. The diesel enters the generator to drive the belt and the pulley, and the eccentric shaft moves the movable plate up and down for the operation. Or use electricity for operation.

But in general, customers will still prepare a backup generator to prevent the mine from being too far away from the city. The power of a PE-400600 crusher generator is 30KW, and the cost is 37-40 yuan if using 30KW electricity (it is different in different countries). The specific generator to be configured is determined by the customer's site conditions and budget.

The performance and the overall structure of the crusher have been improved by reasonable design, thus easy operation and convenient maintenance increase the plant's global availability and profitability.

The development of the PE series jaw crusher demonstrates that the manufacturer has been focusing on customer success by combining the best technology solutions and providing reliability to allow our customers to focus on their own operations.

With professional production technology and export experiences for 40 years, we understand exactly the different needs of customers in various countries. And PE series products are mainly exported to India, Brazil, Vietnam and other countries.

We also have established a sandstone equipment research institute, established an international advanced production line and a first-class modern testing base to R&D the innovative equipment, making the PE series jaw crusher closely fit the customer's actual production needs.

River pebble is a kind of purely natural stone which loses its irregular angle by gravel collision under the action of crustal movement and running water. It is buried in the ground and silenced for millions of years together with the sediment.

There are many pebbles in the sea, smooth, round, and the color more abundant. Therefore, the demand is larger and the price is higher. The Philippines is strategically surrounded by the sea with many rivers on the island, so it is rich in pebble resources.

River pebble has natural characteristics of compression, wear and corrosion resistance which is ideal for green building and important material for making pebble sand after the procedures of crushing, sand making, and screening. It is widely used in the engineering field of water conservancy and hydropower, high-grade highways, bridges, airport runways, municipal works, and high-rise buildings, also as an aggregate for concrete. The pebbles have a high application value for its rich resources and low collection cost.

In March 2017, our promoters contacted a quarry manager from Mindanao, the Philippines on a social platform. The manager told us that he was looking for a suitable machine to reduce the 25-40 cm river pebble to Sand1. -5 mm and 1/4, 1/2, 3/4 stones (6.35 mm, 12.7 mm, 19.05 mm), and expected to process 200 tons per hour.

He also said that he would not start his project before he solved the problem of what kind of equipment is suitable for him, for his mining site was on a remote beach on the island which had rich pebble resources, but the temperature was high, and the rainy season was coming, so the customer worried that the equipment could not withstand the high temperature and humid environment.

After understanding his situation, we designed a sandstone production line suitable for him, including ZSW490110 vibrating feeder, PE7501060 jaw crusher, conveyor, HXCYS400 cone crusher, 3YK2870 vibrating screen, XS3020 sand washer, etc.

Knowing that the customer's site was not very steep, Hongxing advised a fixed machine for him which has a stable operation and less investment than the mobile crusher plant. As for the question that whether can the machine work normally under the high-temperature and humid environment? The answer is yes. But the customer must do the daily maintenance of the machine that we would teach them.

Rainwater enters the inside of the machine, which will corrode the inside of mechanical parts to accelerate mechanical wear and increase mechanical failure. It always causes the bigger problem because of its invisible corrosion, so the operators should take effective measures according to local weather conditions and air pollution at that time to reduce the impact of chemical corrosion on machinery, with emphasis on preventing rainwater from invading machinery. If necessary, you can build a plastic greenhouse or cover.

Every part has its own normal range of temperature. It is necessary to check every the value on various thermometers frequently for its smooth working, otherwise, the machine will be damaged. There are two cooling systems should be paid more attention. For water-cooled machinery, it must be checked before daily work to add cooling water, and for air-cooled machinery, the dust on the air-cooled system should be cleaned regularly to ensure smooth air circulation.

The PE jaw crusher can process materials with a side length of 100-500 mm with the characteristics of large crushing ratio and producing cubic end materials. The PE7501060 jaw crusher is used as the primary crushing equipment for the river pebble with the feed size of 25-40 cm. The big size of the material must be crushed into different granularity by the jaw crusher for secondary crushing.

And the selection is just like this: raw and bigger materials - vibrating feeder - jaw crusher (the primary crushing) - belt conveyor - cone crusher (the secondary crushing) - belt conveyor - vibrating screens (different sizes of end materials). Different granularity can meet the requirements of different specifications of customers.

In the past two years, our crushing equipment has been running smoothly in this mining site. We also conduct regular return visits to the equipment there and help customers with any problem in time. We will also go to the customer's location at any time they need us to inspect and maintain the equipment on the spot, hoping to help our valued Filipino customers reduce losses and expand benefits.

The customer also gave a very high evaluation of our equipment and services. The manager once told the technical manager: "Before you find me, I have contacted several companies from all over the world, but very few of them puts me in the place to consider for me. Only you have tirelessly helped me customize the machine and production plan, and led the technicians to give us professional guidance in production debugging. I am very grateful to you that you helped me complete my project. Now the equipment is running well, and the sand and gravel produced are sold to the construction company. My success is inseparable from your help and guidance."
