Sand is a naturally occurring granular material composed of finely divided rock and mineral particles. The composition of sand is highly variable, depending on the local rock sources and conditions, but the most common constituent of sand in inland continental settings and non-tropical coastal settings is silica (silicon dioxide, or SiO2), usually in the form of quartz.

Sand production line is the mining equipment units that make raw gravel, silica, granite, limestone and quartz materials into aggregate and sand which will be used in construction directly with different size and even cubical shape. Sand production line is widely used in construction projects like building, road construction and railway construction, etc.

ISO 14688 grades sands as fine, medium and coarse with ranges 0.063 mm to 0.2 mm to 0.63 mm to 2.0 mm, sand is commonly divided into five sub-categories based on size: very fine sand (116 mm diameter), fine sand ( mm mm), medium sand ( mm mm), coarse sand ( mm 1 mm), and very coarse sand (1 mm 2 mm). These sizes are based on the Krumbein phi scale, where size in = -log2D; D being the particle size in mm. On this scale, for sand the value of varies from 1 to +4, with the divisions between sub-categories at whole numbers.

In silica sand processing operation, the mined mineral from silica sand quarry deposit will be fed into jaw crusher or impact crusher for primary crushing, after primary crushing; the crushed silica sand is conveyed to cone crusher and VSI crusher for fine crushing.

And then, the fine crushed silica sand will be sieved into different grades by vibrating screen. Washing plant will be applied to clean up the crushed silica sand to remove the impurity and waste materials. SBM has been optimized the silica sand processing plant flow chart, the whole production process work smoothly and high efficiency.

Washing is the simplest and lowest cost technique of cleaning silica sand. In some of the very pure deposits which are without any heavy minerals, high quantities of clay and silt, and no surface staining, washing inadequate to produce acceptable grade product.

In the operation, water is added to the sand and is commonly pumped to a cyclone for desliming. The movement of the slurry passing through the pump and pipeline is sufficient to release the little quantity of fines or clay which is in the ore body. Once the minor quantities of fines or clay have been released from the silica sand they can be removed through a various techniques.

Binh Duong, VietNam Lucky Co, Ltd has 150mm size A grade quartz lumps , and want to convert into 0.1mm to 6 mm size quartz sand and 400 mesh powder. 400 mesh powder is required 480 tons per month, while 0.1mm to 6mm 720 tons per month. Because of A grade quartz costly, they want to take out the minerals through ball mill.

SBM design the complete quartz sand and powder production line. Quartz firstly go through jaw crusher for making small size with 10 to 20mm, then through hopper go into the ball mill. Of course, sbm also supplies services inclusive of installation & trial running.

Shanghai SBM Mining and Construction Machinery Co., Ltd. is a hi-tech, engineering group manufacruring artificial sand making machine. We are specialized in the research, development, and production of industrial crushing and powder processing equipment and pertinent devices. Shibang artificial sand making machines have been sold to 130 countries and areas of Southeast Asia, East Europe, china,South America, the Middle East and Africa etc, and more foreign markets will be promoted in future.

The screening test will show two different types of results., Well aware of the cumulative percentage of sieve sieve.Second, the fineness modulus. These two results are accumulated percentage of sieve the contrast or calculated.

Sand is used to modify soils and construct turf systems for various sports turf applications to promote proper air and water management. Without a doubt sand is the most extensively used amendment on a weight basis to modify turf systems. The use of sand has been extensively reviewed by the United States Golf Association (USGA) in regards to putting green construction. A wide range of sports turf applications such as football, baseball, race tracks and soccer, are utilizing the concepts of the USGA putting green construction guidelines to design and build turf systems for high performance demands. Not all sports programs have the budget for sand based sports fields and will utilize sand in other ways to improve the performance of a field.

Sand is often used in conjunction with the native soil in what is known as a by-pass system. The Cambridge system is a commercially available system that uses sand in trenches and for creating a permeable sand cap over the trenches to remove water during periods of high rainfall. There are several designs that use a by-pass approach with sand. We are often approached about mixing sand with native soils to improve permeability and to lower excessive water holding values. The mixing of sand with soil is not as effective as some are led to believe. If the proper sand particle size is used and the correct amount of sand is added, some benefit can be realized. Usually the amount of sand necessary to increase the overall sand content of the rootzone is so great, that the money and energy is better spent on by-pass approaches or maintenance.

The amount of sand particles in relation to the size of the particle is very important to how a sand will function in various implementations. Most people are familiar with a particle size analysis. It is important to understand the definition of particle sizes and how they are determined. To accurately assess the particle size distribution of a sand or soil, a full mechanical analysis should be performed. A full mechanical analysis involves extracting the silt and clay from the sample and sieving the resulting sand fraction. By removing the silt and clay, the sand distribution is accurately assessed. If a sieve analysis (known as a drop sieve) is performed without the removal of silt and clay, small aggregates of silt and clay can be perceived as sand particles and a false impression of the material may be generated. If you are in the market for a sand for any agronomic purpose, make sure a full mechanical analysis has been performed.

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.

how much does a ton of sand cost? (2021)

Sand, because of its many uses, has become a very important commodity in the world. It can be used for a wide variety of purpose ranging from as simple as filler on your flower vase, layers on your gardens, a material for art crafts and projects, to the some of the most complicated use like manufacturing of glass and sandblasting.

But the major industry that uses different types of sands is the construction. Sands are used in constructing residential houses, buildings, bridges, dams, and just about anything that involves concrete structure.

It is said that cost of sand in itself is very cheap, what makes it worth the price tag it has now are the process it has to go through to get to its intended destination, most likely a construction site. As sands mostly come from quarry sites, all the process involved for it to be available for commercial use hugely affect their price. The extraction from the site, the sifting, the washing, the hauling, the loading, the transporting, the quarry and selling permits, the taxes, among all other cost considerations take part in the costing of sands.

For medium to large projects, sand purchases are typically per ton. To give you an idea, one ton of sand typically covers 35 square feet, one inch thick if you are using either the masonry sand or the river sand. A ton of granite sand typically covers around 75 square feet, two inches thick.

Thecost of sand per tondepends on the kind of sand as there are several types used in many different projects. But the most common type of sands like the ones mentioned above cost around $25 to $40 per ton.

Some construction materials vendors also sell sands per cubic yard, or specifically, per half cubic yard.A cubic yard of sand weighs around 2,500 lbs. while a ton is equivalent to 2,000 lbs. Therefore, a cubic yard is equivalent to 1.25 tons or a ton of sand is equivalent to 0.8 cubic yard.

What is included in thesand pricesdepends on the quantity you intend to purchase. In large quantities, they typically include the cost of the sand material as well as the loading of it into your truck. This is if you think it is cheaper to pick up the sand rather than have it delivered to your project site.

Thesand pricesindicated in different sellers price list are exclusive of delivery fees unless otherwise specified. So, to give you an idea, the delivery charge ranges anywhere between $50 and $100, depending on how far the delivery site is from their storage or quarry site.

The properties of fine sand can be associated with river sand, which, as the name suggests, are obtained from river banks. It is usually whitish-gray in color and is mostly used in plastering. The artificial sand or M sand can also be an alternative to river sand.

This is also known as pit sand which is also popularly known as Badarpur. The sources of this type of sand are deep pits and the coarse sand typically has a red-orange color. Its grains are sharp and angular. They are mostly used in concrete.

the real cost of robotics techcrunch

Before we begin, I feel compelled to make an important disclosure: I love robots! Robots are cool. To me, robots are cooler than people, who are only cool occasionally. I especially love industrial robots: They help us make things.

Now please allow me to make an obvious observation: Like me, many folks think robots in general, and industrial robots in particular, are very cool. Some of these folks hold high offices in various business enterprises, where they broadcast their love for robots into their working environments.

The medias current infatuation with industrial robots and automated manufacturing has these guys whipped into a frenzy. I know how they feel, because I feel the same way. How else can you feel after watching a video showing the production of motors for Dyson vacuums? The video is sexy as hell shiny machines executing a complex dance in perfect unison. Its a city full of wonders, completely devoid of boring humans.

The conclusion is inescapable: Sir James Dyson must be the overlord of robots. That is, until you see the video on how Tesla Model S is made. Another professionally put-together report from the land of (almost) no workers.

There are many videos like that, and the media is rebroadcasting them with enthusiasm. This leads me to this question: Why the renewed interest? Robots were perfectly capable of automatically manufacturing complex things decades ago. Just look at industries with products that cant be directly handled by humans: The semiconductor industry, where the product is too small for human hands, has been building vast automated facilities since the IC revolution began and the American auto industry started to fill factories with robots back in the 1970s.

Although all of the above are true to some degree, the simplicity of media coverage distorts the real situation. Afterwatching numerous videos showing cool automation in action, it would be easy for you to get the wrong idea about how much effort it takes to automateanything.

I will argue, based on my own and my peers experience, that a lot of folks imagine the process of bringing a robot onto their production floor as, literally, bringing a robot in. You buy a robotic arm, you install that robotic arm, youre done.

Its hard to blame them. Robotic manipulators are what they see in videos. If you hear the words industrial robot, what pops up in your mind? The arm! Get one or a couple of these and you are on the way to your companys automated future. If only it was that simple!

Because you know that you definitely need a robotic manipulator, you start your purchasing or your mental journey from getting that arm. So you buy an ABB,KUKA,Toshiba,EPSON or some other brand you saw at the robotics trade show you visited recently. Depending on the brand, your outlay for the arm is perhaps $30,000-60,000. Despite the high cost, that arm is literally an arm. No torso. No wrist. No fingers. No eyes. And no brains (Ill get to this later).

Next, you find out that you cant simply install your robot on any desk. No. It must be a heavy-duty, purpose-built pedestal. These things have enormous weights; they are expensive, too expect to spend several thousand dollars.

But wait, theres more. Your robot needs a cage unless its one of those new collaborative robots like UR-10 from Universal Robots. Because they are allowed near people, they move like yoga instructors, putting you to sleep in the process. If you care about doing things fast, youll buy a speedy robot and it will have to be caged. The cage will need to come with some safety equipment, like an emergency stop button, safety sensors and so on. Chalk up several more thousand dollars for the cage and all that safety stuff.

Next, youll need to take care of something called an end effector. That is the part that attaches to the business end of your robotic arm and allows it to do useful things. End effectors vary, from grippers with fingers for holding things to vacuum headsto electric screwdrivers to an endless array of specialized contraptions. Chances are you wont find any suitable end effector for your application, so someone will have to build you one. Budget a lot of money for this part of your project.

Human hands are extremely versatile and can do thousands of different jobs. Not end effectors. Your robot will probably have to be equipped with several end effectors for handling different production steps. This will involve the use of a so-called tool changer. Its just like in Japanese cartoons. One moment that giant robot holds a bazooka, the next its a ray gun.

With a tool-changing system, like the one made by ATI-IA, your robot will be able to quickly change between, say, an electric screwdriver and a suction gripper. The bad news is that tool changers are so expensive that adding such a system will easily cost you around 30 percent of what you paid for your robotic arm.

Next, youll need to think about giving that arm of yours some ability to sense. Most robots dont come with force feedback. They boldly go where you tell them to go, no matter how many things get smashed along the way. A typical robotic arm with a gripper is about as sensitive as a crab claw (no offense to crabs). A force-sensing accessory will solve that, to a degree, but it will also set you back several more thousand dollars.

Wait, you arent there yet. Now you need to think of a way to hold your parts in production, i.e. parts that your robot will be working on. Humans come with two hands. We can hold a screwdriver in one hand and secure the part on which we are workingin the other. Try doing any kind of assembly using just one hand. You wont get very far. Well, thats the situation your robot will be in,constantly, unless its one of those cute two-armed ABB Yumi robots (there is nothing cute about their price; you can buy two or three one-armed servants for the price of one Yumi).

So, in order to hold your parts in production in place, youll need to come up with fixtures and contraptions that are unique to whatever it isyou are manufacturing. There are many ways to do this stuff. For example, my company supplies a construction system called UniQb. You can quickly build one-off fixtures and rigs using its beams. This part of your project may not be very expensive (in comparison to everything else), but it will consumequite a bit of time.

Alternatively, you can assign a worker who will service the robot while contemplating a philosophical question: Who works for whom? Does the robot work for me or do I work for the robot?

This step handled, you will need to think of how your robot will get the parts to work on and output the fruits of its labor. Robots cant (yet) run to the warehouse and cart back a bunch of parts. You robot is like a master craftsman sitting in the middle of a studio. Everything must be brought to it. For small parts, such as screws, you will need to install screw presenters machines that offer screws in the right orientation. Larger parts will need to come on conveyor belts or some other means of transportation. Alternatively, you can assign a worker who will service the robot while contemplating a philosophical question: Who works for whom? Does the robot work for me or do I work for the robot?

The next step is to equip your mechanical monster with eyes. With the exception of the aforementioned Yumi, which, in the appropriately mutant fashion features eyes on its hands, most robots arrive at your doorstep completely blind.

You will need to install a vision system consisting of one or more cameras and a processing unit. You will also need to arrange ideal lighting conditions: Cameras are not like human eyes. Too bright or too dark, and the system wont work. Also, robots mostly see in 2D. There are some new 3D vision systems on the market, but these are still prohibitively expensive. A good vision system will cost you several thousand dollars and a lot of trial and error until you get it to work right.

Also, dont forget about electric power and air supply. Many robots will require industrial power (not thepower available on tap from your wall outlet). Your system will almost certainly use vacuum grippers or something else that requires air. Robots dont come with compressors. You will need to buy and install one. More $$$ spent.

Are we there yet? Nope! All this extra stuff you now have around your robot will need to be hooked to a single control system that opens and closes valves, activates servos, senses the position of things and so on. Such jobs are typically accomplished with programmable logical controllers (PLCs) or embedded computers.

Last but not least: programming. This part is particularly fun. You will need to teach your robot how to do anything useful. Hello, disappointment. We all grew up watching Star Wars, so we automatically attribute some intelligence and magical powers to our mechanical helpers. Forget it. Robots are not smart. In fact, they are plain dumb. You will need to teach your robot literally every tiny little move. There is virtually no self-learning. Expect a lot of labor. You will be trying, adjusting and, when you thought you were done, youll find yourself coming back to adjust some more.

All these steps Iveoutlined require you to be a very skilled professional in a multitude of disciplines. Chances are that you arent and even if you are, its unlikely you have time to deal with all this complexity. This is why you will probably hire an integration company to put the system together for you for a price tag that is twice higher than the sum total of all the parts involved.

In the end, you will look at that robotic arm you started your journey with and realize that the arm is but a tiny part in the long list of equipment that had to be provisioned, installed and configured in the name of your automation project. You see now what it took Sir Dyson and Mr. Musk to fill their factories with hundreds of robots? They approved oceans of work, hundreds of thousands of hours of human planning and design and tens of millions of dollars in equipment costs.

And now for the worst part Here it comes. Da-dah! These futuristic production lines you see on TV and YouTube are mostly built to handlejust one product. Change the product, and you need to redesign your production line. You dont just tell your robot to stop doing this thing and start doing that thing right from tomorrow morning. You start retooling and retooling is expensive and time-consuming.

The U.S. auto industry with its futuristic robots learned this the hard way, while the Japanese (whom we firmly associate with robots) did not go overboard and simply stayed with lean production teams of human workers. Take heed! Before embarking on your automation journey, count how many years of human salaries you will be able to pay by NOT investing into your smart robotic manufacturing cell.

Have I just put you off robotics? I hope not! Like I said at the start of this conversation, I love robots! Robots are cool. There are many excellent reasons to use them. We humans are unpredictable and difficult, and as time goes by we become less and less inclined to take on factory jobs.

Automation is coming, and robots will eventually take over our production lines. I just want you to know that todays real-life robots are nothing like what the media makes them out to be. Proceed with caution (and deep pockets).
