Our technology has been proven over 10 years to help the customers maximise the quality and value washed sand.
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.

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, 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.

In the sand artificial making process(sand plant), the raw materials are evenly fed into the jaw crusher machine for primary crusher by the vibratory feeder. Then the crushing materials are conveyed to impact crusher and vsi sand making machine for secondary crushing(fine crusher). The belt conveyor transports the finally crushing materials to vibrating screen for separation. The require sand size product would be sent to the sand washing machine for clearance. Unrequested product will be returned to the sand making machine for repeated crushing until getting all required size. The process of artificial sand making is complete.
There are mainly three steps of crushing, washing and screening in the artificial sand making process. The crusher machines of crushing step may employ use jaw crusher, impact crusher, cone crushing, hammer crusher, sand maker. The artificial sand size different, the crushing equipment is different. The equipment of washing sand step is wheel sand washing machine or spiral sand washing machine. Spiral equipment washes much cleaner. Then the last step is to use sand screening machine for sand separation.
There are many materials that can make manufactured sand. For example, granite, basalt, river pebbles, pebbles, limestone, calcite, andesite, rhyolite, Diorite, diabase, sandstone, tailings, slag, quartz, etc. They vary in strength and grain size of artificial sands is because of the rock different. Exposition of the use of some rocks for making sand as follows.
Basalt The sand made of basalt mixed with concrete that can reduce the weight of concrete. And it is still very firm, also sound insulation and heat insulation. It is a good aggregate of lightweight concrete for high-rise buildings.
2. Operation and Maintenance. Standard operation and regular maintenance can improve the sand production rate of the sand machine. If not, the crushing equipment wears parts will wear speed up, and reduce equipment life. The rate of sand making machine lessens.
3. Quality Sand maker quality is good, not only energy-saving, environmental protection, and can easily achieve the expected output of equipment. JXSC who crushing machine manufacturers use new-high-wear-resistant materials and international more advanced production technology. Our equipment can meet the production requirements of customers. Provide a favorable guarantee for continuous, efficient and safe production
4. Project design. The design of the whole sand plant must rationalize. The production plant not only requires a reasonable production capacity of the sand making machine, but also requires that the handling capacity of the jaw crusher, the cone crusher and the belt conveyor match it. Otherwise, the final sand production rate will definitely fail.
Artificial sand is produced by reducing larger pieces of aggregate into sand-sized aggregate particles. Manufactured sand can be manufactured to be a certain grain size that the buyer chooses, while natural sand can be a mix of coarse and fine grains. Manufactured sand tends to be more angular and flaky due to the crushing process. Highly angular particles tend to increase the paste content of concrete because additional lubrication is required for particles with sharp corners. Supplies of artificial sand are limited only by the capacity of those making it, and where natural sand is in short supply or logistically difficult to obtain, artificial sand is a better solution.
Natural sand has an ideal shape for use as fine aggregate in concrete. The natural sand particles are well-round and are usually nearly spherical. Spherical particles decrease the percentage of voids within the concrete mixture so no additional paste require to fill these voids. Well-shaped natural sands are ideal for workability of mixtures. Natural sand does not require more water to enhance the workability of the mixture so the amount of bleed water in the concrete will not be increased.
Long ago, when the industry was undeveloped, the river sand was not strictly controlled and could be mined by everyone. The method of mining mainly depends on manual mining. When the water is shallow, the sand-picking tools like Dustpan are put on the bottom of the river, and the sand-passing boat is pulled up bit by bit by manual force. Shipped Ashore, hand-picked to the sands.
Now, it uses mechanically mined, using gravel pumps to suck the sand directly from the river, and then loaded into trucks or piled up in coastal sand fields. But because excessive mining which destroyed the ecological environment, now, many countries are strictly prohibited from Mining River Sand. Therefore, the Walkerpump gravel pump is hardly used for sand mining, but for dredging, gravel suction, dredging channels, mining, and metal smelting slag transportation.

The artificial sand production line is a special production line equipment for the production of construction sand and stone. It saves 50% of energy compared to traditional sand-making machines. It can make materials such as rock, gravel, and river pebbles into various particle sizes that meet the requirements of construction sand. The sand made by the artificial sand production line has uniform particle size and high compressive strength, which is better than natural sand and ordinary hammer sand blowers. The sand produced is more in line with construction requirements and can improve the quality of construction.
During the working process of the sand production line, the large stones are evenly fed into the jaw crusher by the vibrating feeder through the silo for coarse crushing. The coarsely crushed stone is sent to the cone crusher or impact crusher by the belt conveyor for medium crushing. The crushed stone is sent to the vibrating screen by a belt conveyor for screening, and the finished sand (under the screen) is sent from the belt conveyor to the sand washing machine for cleaning and then sent to the finished product pile by the belt conveyor. Large-grained stones (over-screen) are sent to the vertical impact crusher (sand-making machine) by the belt conveyor for fine crushing. The crushed stone is sent to the vibrating screen again by the belt conveyor for screening, thus forming a closed circuit for multiple cycles.
The sand washing machine is mainly used in the screening and washing stage of the sand production line. In the traditional wet processing technology of artificial sand, the spiral sand washing machine used for the washing and dewatering of artificial sand, the loss of fine sand in the artificial sand can hardly be controlled. The use of a fine sand recovery machine can effectively reduce the flow of fine sand and reduce the content of stone powder in the tailwater, which solves the problem of high fineness of finished sand and low stone powder content in the artificial aggregate processing system.
Sand products often contain a certain amount of soil and dust. If these soils are cleaned, the use of sand will be affected. Therefore, at this time, it is necessary to use sand washing equipment for cleaning, and the sand and gravel after cleaning can be used in our project construction. The sand washer can also improve the purity of the sand and prevent it from sticking together during stacking. Wheel sand washer equipment generally has a capacity of less than 80 tons, so it is suitable for small and medium capacity sand production line systems.
