A Stone Crushing Plant is one-stop crushing installation, typical materials like limestone, granite, river gravel, basalt, etc., the plant produces different sizes of gravels and sand which can be used for constructions.

Stone Crushing plants may be either fixed or mobile. A stone crushing plant has different stations, primary, secondary, tertiary, etc., where different crushing, selection and transport cycles are done in order to obtain different stone sizes, for fixed plant different stages combines together to form a complete stone crushing plant.

Raw materials are evenly and gradually conveyed into jaw stone crushing equipment for primary crushing via the hopper of vibrating feeder. The crushed stone materials are conveyed to crushing plant by belt conveyor for secondary crushing before they are sent to vibrating screen to be separated. After separating, qualified materials will be taken away as final products, while unqualified materials will be carried back to the stone crushing equipment for re-crushing. Customers can classify final products according to different size ranges, also according to different requirements, final products sizes can be adjusted from the crusher machines.

2 types of concrete crushers | hxjq

The rapid development of urbanization has resulted in the accumulation of a large amount of waste concrete, which not only occupies land resources but also pollutes the air and the environment. Therefore, the recycling of waste concrete has become an important issue that the government needs to solve.

Abandoned concrete blocks are high-quality concrete aggregates which have many advantages. For example, after the buildings are dismantled, the high-quality concrete blocks and silt after crushing and screening can be used as recycled coarse and fine aggregates for concrete. The fine powder can be directly used as the raw material of cement. The concrete prepared from recycled cement and recycled aggregate can enter the next cycle, which realizes zero waste discharge throughout the whole cycle.

Concrete, cement and other wastes in construction waste can be used as building aggregates and recycled brick raw materials after being reasonably crushed, screened and crushed. And the main equipment used for crushing concrete can be divided into two types: traditional fixed crusher and mobile concrete crusher, among which small crushing equipment is favored by users.

Although the compressive strength and hardness of concrete are not high, due to the porosity and the formation type, the concrete has good toughness and can buffer the crushing force, which causes low crushing efficiency. So, what kind of crusher should be selected for concrete crushing? In the process of crushing waste concrete, according to the working principle of more crushing and less grinding, it is necessary to carefully configure the concrete crusher equipment.

Jaw Crusher, also known as concrete crusher, is usually used as the primary equipment for concrete crushing. It is also suitable for metallurgy, mining, construction, chemical, water conservancy and railway sectors, and used as a device for fine and medium crushing of ores and rocks with compressive strength below 250 Mpa.

In recent years, the small jaw crusher has been favored by foreign users because of its small size, easy transportation and installation, low price, and fast profit. The models like PE-150250, PE-200350 and PE-400600 have become the best choice for customers to crush concrete.

After the rough breaking, steel and iron equipment are added to remove the steel bars and iron blocks in the waste concrete, which will eliminate the damage of steel bars and iron blocks to the equipment without affecting the production. Generally, the impact crusher, the fine crushing jaw crusher or the cone crusher is used as the secondary crushing to crush the material to less than 2 cm, and the selected granularity can be basically achieved.

For smaller discharge sizes, a three-stage crusher can be used, for example, the fine crushing crusher or the roller crusher is used to further crush the ore to less than 10 mm. In the actual production, the suitable crusher can be selected according to the size of the concrete block. It can be combined in single or multi-machine operations, both of which have the characteristics of simple operation, strong controllability and high production efficiency.

In the international environment of the crusher industry, besides the traditional jaw crusher, high-efficiency and environmentally-friendly construction concrete crusher will be the trend of future development.

In view of the characteristics of concrete waste, Henan HXJQ Machinery designed a concrete crushing equipment-mobile concrete crusher. The waste concrete after crushing can be used for reinforcing the foundation, producing bricks, cement, etc, not only achieving its values but also solving the issue of land and environment problems, which can be described as two-fold.

The mobile concrete processing station produced by HXJQ Machinery adopts multi-stage combination mode, which includes jaw crusher, impact crusher, cone crusher and vibrating screening equipment, conveyor belt, etc. Generally, the concrete crushing station is composed of a concrete crusher (sand making machine), a screening machine, a feeder, a conveyor belt, a steel frame, a drive system, an electric control system, a motor unit and the like.

The concrete material is sent into the crusher by the feeding equipment, and the crushing machine converts the large concrete into gravel. The finished product which meets the standard is transported by the conveyor belt to the stacking place, and the products which don't meet the standard will be transported by the other conveying belt to the crusher again until it is qualified.

The integrated vibrating screen, feeder and the under-belt conveyor, the vibrating screen and the crusher integrated into the vehicle can reach any position on the working site under any terrain conditions. Thus the mobile concrete crusher has many advantages like reasonable material matching, smooth flow, reliable operation, convenient operation, high efficiency and energy saving.

1. According to the driving way, it is divided into tire type and crawler type: the tire type concrete crushing and sorting machine needs semi-trailer traction to run, while the crawler type can be remotely operated with buttons. Relatively speaking, the latter is more intelligent and the price is more expensive.

2. According to the function, it is divided into crushing type and sand making type: the concrete crushing and screening machine includes a combination of crushing equipment such as jaw crusher, cone crusher and impact crusher. The sand making type is mainly equipped with sand making machine and hammer sanding machine.

The mobile crushing station can prevent and control environmental pollution, improve the ecological environment, and protect natural resources. The size and model can be designed according to the different production needs of users. According to the statistics of the HXJQ machinery, the small mobile crusher is chosen by more foreign users because of its reasonable price, high quality, convenient transition, operation and maintenance.

A project introduction of construction concrete treatment: in October 2018, a customer found HXJQ, and hoped that we could provide him with the complete equipment for breaking construction waste. Our technical manager quickly contacted him and learned that the customer had a large amount of construction waste to be disposed of.

From the perspective of economic foundation and practical operation, the technical manager recommended the fixed crushing station to him and designed a complete set of equipment suitable for his actual needs. In the end, the customer introduced the PE-400600 jaw crusher and PF-1010 impact crusher produced by our company to break the concrete waste. The finished sandstone is used for brick making, roadbed materials, etc., and the separated steel is recycled.

The pretreated concrete with reinforcing steel is sent to the jaw crusher for initial breakage by the conveyor belt, then effectively separated by the iron remover, and sent to the impact crusher for fine crushing. The crushed material is sieved by the vibrating screen. The finished material is output by the conveyor. If the material does not meet the specifications, it will continue to return to the impact crusher and break again.

The development and utilization of waste concrete as a recycled material solves the problems of a large amount of waste concrete treatment and the resulting deterioration of the ecological environment; on the other hand, it can reduce the consumption of natural aggregates in the construction industry, thereby reducing exploitation of the natural sand and gravel, which has fundamentally solved the problem of the depletion of natural aggregates and the destruction of the ecological environment because of the lack of sandstones.

Under this circumstance, the crusher plays an irreplaceable role in the recycling of materials. Whether it is the traditional fixed crusher or the latest mobile crusher, both of them have their own advantages. As long as the size of the stone produced by the equipment can meet the standard, it is a good crusher.

types of rock crushers | quarry crushing equipment | kemper

Do you need to process sand, gravel, minerals, rock, or other aggregate products and have not yet purchased or leased crushing equipment? Theres no questionyou need to work with a capable and professional material handling equipment design and engineering company dedicated to selling, renting, and installing the best new crushers for your needs.

However, if youre new to the aggregate processing industry, you probably have a lot of questions about rock crushers. As foundational material handling equipment in all plants, crushers need to coordinate seamlessly with screens, conveyor systems, and washing equipment.

It is common to use multiple crusher types within a project and set them up as stations in a circuit format to perform the necessary material reduction work. In many cases, primary, secondary, and tertiary, and quaternary stations are installed to reduce the rock to the desired size, shape, and consistency.

For instance, if the final size of your product only needs to be between 4 inches and 6 inches, a primary jaw or impact crusher can accomplish your goals. However, you will likely require a much finer product, and that means incorporating up to threeor even fourstations with a variety of crusher types.

As the first stage in a crushing circuit following extraction from a mine site, (or in the case of recycled asphalt production, delivery to the RAP processing plant via truck transport), primary crushing reduces material to a size and shape that can be handled by the secondary crusher.

Typically, the minimum setting on most primary crushers will be about 4 to 6 inches, as noted above. Compression-style jaw, cone, impact crushers, and gyratory crushers are most often appropriate as primary crushing equipment types, though there can be overlap between primary and secondary crushers as far as suitable types.

In secondary crushing, reduction ratios become an essential consideration. Knowing just how fine you need your final output to be, along with the feed requirements of your tertiary or final reduction crushing station, will help you determine how much reduction needs to take place within this stage.

Cone crushers are often placed within the secondary crushing station because they are versatile in terms of feed, closed side setting, speed, and throw. With cone crushers, though, it is essential to operate them at consistent choked settings to keep productivity up.

The goal of the tertiary (third), quaternary (fourth) or final reduction stage of the crushing process is to size and shape rock or other material into a marketable product. Again, there may be overlap between stages in terms of which crusher styles work best.

Sandstone, limestone, gravel, and granite are arguably the most common aggregates used in the construction industry today, but these rocks have very different hardness and abrasiveness characteristics.

The answer might be three to four if youre talking about setting up stations in a complete rock crushing plant. Those are the primary, secondary, and tertiary/quaternary/final reduction rock crushers, which we covered above.

Of course, there are also different styles of rock crushers. Compression-style jaw and cone crushers, for example, fit into the various stations in a crushing circuit (depending on factors like the sizes, varieties, and hardness of the rock you need to crush, as well as the necessary output).

The number of crusher types in terms of style and configuration can be more challenging to quantify, as there are lots of ways to customize rock crushers. However, youll find four basic designscone, jaw, gyratory, and impact crushersoperating within many crushing plants.

Jaw crushers are also known as rock breakers and are used to break up larger, harder materials into more manageable pieces. They tend to do well with many different types of materials and dont display as much wear and tear as impact-style rock crushers. They also produce minimal fine materials and dust, though the finished product with this type of rock crusher almost always requires secondary crushing.

To learn more about jaw crushers, youll want to catch our previous blog post all about these tough pieces of material handling equipment and the most common questions operators have about jaw crushers.

Cone crushers can accept medium-hard to very hard and abrasive feeds that might be dry or wet, though not sticky (whereas gyratory crushers are better at handling softer, dryer feeds). Their output will be a relatively cubical product, with a reduction ratio of about 6-to-1 through 4-to-1.

Impact-style crushers include VSIs, as well as horizontal shaft impactors (HSIs), and are best used with less abrasive rock types, like limestone. These types of machines break apart material by the impacting forces of certain wear parts known as blow bars and impact plates or toggles.

Some operations also use impact-style crushers after they have already used a different type of rock crusher that produces a more elongated stone. This helps further shape the crushed material into a finer consistency with a more cubical nature.

Impact crushers tend to be less expensive than compression crushers (aka cone and jaw crushers, which we already covered) and have a higher reduction ratio. They can also break sedimentary deposit-type rockslimestone and similaralong natural lines, which rounds off sharp angles and weak edges. This can produce a result that is more sand-like in nature.

Drawbacks of impact crushers include their tendency to produce an excess of fine materials if used with softer rocks. Impact rock crushers can also require frequent part changes and can create a large amount of dust that can be an issue on some worksites.

Stationary plants have long been preferred because they feature a higher capacity and efficiency and lower production costs with easier maintenance. They also have historically featured a lower energy cost if you have on-site electricity, and no additional equipment is needed to move them from place to place.

Its true that portable material handling equipment already offers unmatched production flexibility. For instance, if you need to move your crushing plant more than once a year to multiple job sites, you are likely better off investing in portable equipment.

These self-contained plants are better suited to smaller projects and can be moved from project to project as necessary. They are often still not quite as efficient and have less capacity than stationary plants, but they can be more cost-effective in the long run if you have multiple projects in different areas.

Many different industries have a solid foundation rooted in aggregates. Recognizing the extensive use of these aggregates motivates us to continuously create and improve our rock crushing equipment to help you increase production, decrease maintenance and improve the overall efficiency of your operation. When it comes to quality and efficiency, our rock crushers are perfect for the job.

Primary crushers are first in a typical size reduction operation. Primaries like our Mega-Slam horizontal shaft impactor are commonly used in the aggregates industry to handle large feed sizes.The Grand-Slam HSI is well suited as secondary crusher for aggregate production for a wide range of materials including limestone, frac sand, gravel, stone, and more. Tertiary crushers are commonly used in the aggregates industry for final particle shaping to increase cubicity, and to produce a product size beyond what is capable from a primary or secondary. This stage of crushing is typically accomplished using a vertical shaft impactor or cage mill.

Specialty uses of limestone include the manufacturing of pharmaceuticals, toothpaste, paint, paper, caulking, and glass. Flooring materials, carpet, and plastics all contain finely ground recycled limestone. Common antacids are virtually 100% finely ground limestone. Farmers can reuse limestone to neutralize acidity in their soils, saving money by reducing fertilizer use while improving crop yields.

The 4-Row Cage Mill allows Aglime producers to meet most state Aglime specifications in open circuit. It will economically produce Aglime to any specification for both large and small producers. The 4-Row Cage Mill feed does not have to be dry. Clogging, jamming and plugging are eliminated. Available with capacities as low as 5 TPH up to 100 TPH, the 4-Row Cage Mill produces consistent product quality.

Stedman Machine and Innovative Processing Solutions, an affiliate of Stedman, worked with Duff Quarry Inc. to incorporate two large industrial crushers to handle the size of limestone crushed annually.
