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.

another high quality sand production line by dry sand-making method in changde, hunan

another high quality sand production line by dry sand-making method in changde, hunan

Limited by the policies, the supply of natural sand is decreasing sharply while the traditional machine-made sand has some weaknesses like big fine modulus, low yield and severe dust pollution. Foe Hunan a huge potential market, the advanced, eco-friendly dry-type sand-making technology may be the best choice for the future of enterprises.

With the issue of Trail Measures of Regulating River Sand Quarrying in Hunan Province in 2012, the quarrying of natural sand has been limited continuously. Meanwhile, traditional machine-made sand production line has such problems as poor grading, big fine modulus, mixed concrete with low strength and water pollution, etc., which incur criticisms. In light of this, LONGCHENG Inc. , the local famous manufacturer of concrete aggregate, purchased from SBM the world-class dry-type sand-making system---VU Aggregate Optimization System and put it into use in the late 2015, absolutely solving the problems existing in wet-type sand-making system like big fine modulus, low yield and severe dust pollution.

Hunan is one of provinces having abundant natural sandstone with the high quality natural sand distributed in the Xiang River basin and Dongting Lake. However, in recent years, the lag in traditional sand production technology and the disorder of construction-use sand market led more and more unauthorized quarrying which threatened the amount of sandstone resource in Hunan and increased the quarrying cost. After the issue of Trail Measures of Regulating River Sand Quarrying in Hunan Province in 2012, the quarrying of natural sand has been limited continuously.

Under the circumstances that natural sand gets less and less but more and more expensive, machine-made sand, as the substitute, develops fast, filling the gap of natural sand market. So far, Hunan has launched multiple policies to improve machine-made sand projects. In some areas, industrial slag, construction wastes and barren rocks are used to make sand to develop recycling economy so that the machine-made sand industry looks like a both traditional and emerging field.

Traditional machine-made sand production used the wet-type sand-making system which controls the stone powder content through washing gumming technology. In the process of washing machine-made sand, part of the fine particles below 0.6mm would be removed with the mud, impurities and stone powder below 0.075mm. This would cause the poor grading, big fine modulus and concrete with low strength. Meanwhile, it also reduces yield, wastes resource and leads water pollution impeding clean production.

Given the heavy demand for high quality machine-made sand in Hunan and the weaknesses brought by the wet-type sand-making system, sand-making enterprises have started to search a new technology to replace it. So this time LONGCHENG.Inc. selected SBMs VU Aggregate Optimization System which uses unique dry-type sand-making technology. It avoids the problems in dry-type technology and can process the high quality machine-made sand to replace natural sand. The VU system, therefore, got the high appreciation from cooperative enterprises of Hunan.

In order to satisfy the increasing demand for high quality sand and the performance requirement of concrete and mortar, SBM spent 5 years developing VU system at the specialized aggregate optimization test site with over 30-year experience in this industry.

VU Aggregate Optimization System is a scheme system designed to produce high quality machine-made sand, which overcomes the problems in the sand-making technology including crushing, grinding and separating.

The new generation of VU Sand Making Machine firstly realizes the grinding technologies including high-frequency "stone hitting stone" and "material cloud". Compared to VSI Sand Making Machine, the VU the system increases the sand rate and fine sand rate by over 10%.

The combination of crushing, screening and powder separating, the Screen can finish material screening and stone dust removing at the same time because of its full closure, dust removal using negative pressure and uniform screening.

Wind volume and flow duct can achieve continuously online precise adjustment without replacing the screen mesh and other parts. The fineness of final sand is controllable within 2.5-3.2, the powder content within 3-15%.

Imitating formation principle of natural sand, the machine adopts the global pioneering technologies of "low energy crushing and dressing" and "self-grinding via falling mode" .,which can validly remove the edges on the surface of final products and increase the volume of fine sand about 0.6mm, the voidage reduces 1-2%, the flow time 5%.

The design of automatic monitoring and material discharging of fine ore bin makes the fine material storage and transportation possible by pressing a button. It greatly reduce labor intensity and operation cost.

The controlling and monitoring tasks of all machines are integrated into the central control system, which greatly simplifies the operation process and ensures the safe, continuous and stable production.

Setting and keeping the optimal operating parameters is available. And the quality of products is stable. This system can maximize the productivity and keep the overall efficiency at the highest level.

Screening and grading: the crushed stone is evenly fed into the VU FM Control Screen through feeder. Grading the machine-made sand is to precisely control the graduation of machine-made sand. Then the unqualified materials would be sent back into the crushers to be crushed again and redundant stone powder would be collected by the Dust Separating and Collecting System.

Moistening and transportation: The re-optimized machine-made sand enters into the humidifying blender to be moistened. The water content of final sand is controlled to further ensure the quality of produced sand.

Transportation, storage and packing: The redundant stone powder is collected by the pulse dust collector and then sent into the finished product tank for storage through pneumatic carrier. Finally, the final products are transported after being packed.

After having a clear understanding of various condition of the customer, we finally drew a proper layout scheme after discussing the specific conditions, conceiving and appraising scheme. It ensures suitable, economical and the maximization of profits production line customized for the customer.

SBM developed the full-automatic VU Aggregate Optimization System which is designed to meet the demand for grading/fineness modulus and powder content on machine-made sand. It overcomes the problems existing in the optimization process including crushing, grinding and separating.

SBM has a skilled and experienced after-sale service team. All members are earnest and innovative. So far, thousands of engineering projects has accepted the installation and commissioning service. Meanwhile, SBM would help customers train their operating staff until they can operate the production lines independently.

In order to make customers understand the machine maintenance and repair, SBM supplies customers with the machine instruction manual that shows the detailed analysis of machines and marks each part. It not only helps customers know the machine structures but also makes the part replacement easier.

The whole VU Aggregate Optimization System production line offered by SBM is compact structurally and reasonable on design. This production line achieves maximizing productivity and minimizing operation cost. The whole production process is dustless and the redundant stone powder is recycled. The produced stone and sand has perfect grain shape. The sand grading is satisfying. So concrete preparation in the mixing plant is very stable and reduces the use of cement. The cost of production is, therefore, reduced.

Grading: For dry-type sand-making system, after the powder separating machine, the soil particles in the artificial sand can be removed and the sand can meet the standard for construction. Besides, the stone powder content in artificial sand can be controlled by the powder separating system under the national regulations so that the compressive strength and mixability of concrete can be increased. For wet-type production, in the process of sand-washing, the washing sand would be removed with stone powder, leading the shortage of washing sand in finished sand product and influencing the grading of sand.

Cost: The production cost of dry-type sand making production line is relatively lower for it uses the high-efficiency powder separating machine to separate sand and powder and doesnt need a lot of water to wash.

Environment: Unlimited by water and environment, the dry-type sand making system can make sand in the water-poor areas. But for wet-type sand making production line, making sand must be carried out in water-rich areas. And the production is impossible in winter in high latitude zones.

Environmental protection: Water in the dry-type production line is not required. The stone powder in the production can be used reasonably. So, to some extent, the water and minerals are saved. Moreover, it brings no sewage and sludge. It is more environmental than the wet-type sand-making production line.

Do you want to learn more about the Masa sand lime brick manufacturing process? Inform yourself using the interactive step by step system, as to how a sand lime brick is produced from various raw materials.

Sand lime bricks consist of the two raw materials sand and lime only. For the manufacturing process, water is required in addition. The raw materials that are mostly supplied from local extraction places are stored separately in raw material silos. On the way to the silos, the sand passes a screening station to separate oversize material.

Masa sand lime brick making plants are designed to use at least two different types of sand. The advantage for the customers is that the product quality can directly be influenced by a specific mixture of the different types of sand.

The raw materials sand, lime, and water are exactly dosed and weighed in individual scales and fed into the intensive mixer. In the mixing process, a homogeneous and highly disperse sand lime compound is generated.

By means of transport devices (e.g. belt conveyors and bucket conveyors), the sand lime compound is fed into the reactor . The number of reactors depends on the number of presses. Typically, one reactor per press is used. Advantage: With the help of the Masa mixing plant control system, each press is always supplied with an optimum sand lime compound, also in case of different products.

Inside the reactor, the lime is turned to calcium hydroxide by means of a chemical reaction that is triggered when water is added. This process is completed after approx. two hours, and processing of the sand lime compound can be continued in the press.

Between the reactor and the press, there is a double shaft mixer. To provide the double shaft mixer and the press with constant quantities of sand lime compound, the reactor outlet is equipped with a special discharge system developed by Masa. With the help of the Masa press control system, the quantity of the sand lime compound is adapted to the manufacturing process.

In fully automatic hydraulic presses, the sand lime compound is pressed to bricks. The Masa press control system provides for a uniform compaction of the sand lime compound until the required final height and density of the products is reached.

Different moulding tools enable the manufacture of different brick sizes. Depending on the type of tool, it is possible to manufacture perforated or solid bricks with or without tongue and groove or holes for handling or chamfers.

A brick placing automat takes the fresh bricks from the press and smoothly places them on a hardening car. The Masa press control system enables a precise and space-saving loading of the hardening cars so as to make an optimum use of the autoclave capacity.

When the hardening car has been loaded completely, it is moved to a transport platform via a rail track system. Depending on the factory capacity, up to 8 hardening cars can be moved so that loading and unloading of the autoclaves can be carried out quickly.

From the transport platform, the hardened sand lime bricks are transported to the packaging plant on the hardening cars via a rail track system. To guarantee a fast discharge of the autoclaves, a complete autoclave filling can be stored intermediately in front of the packaging plant.

Masa recommend to package the finished products in that way that they are protected from dirt and moisture before they are removed from the factory. Depending on the plant concept, this packaging process can be carried out automatically or semi-automatically.

top 38 q&a on complete set granular production lines

top 38 q&a on complete set granular production lines

Dear sir, we are a leading glass bottle making company India with any our own Quartz sand manufacturing facility. During the manufacturing, we are generating a lot of sand dust & fines (100 to 400 mesh) which we are not able to use. Now, we are planning to use the Sand dust & fines in manufacturing of the glass bottles by using it instead of the manufactured sand in the glass furnace. Since the sand dust & fines cannot be fed into the furnace directly as it is very fine, we need to form small pallets instead of the manufactured sand in the glass furnace. Since the sand dust & fines cannot be fed into the furnace directly as it is very fine, we need to form small pallets in a Palletizer before feeding in the furnace. Since the adhesive property of the sand dust & fines is very poor, we are adding some binders before palletizing/granulating (balls of dim= 2 to 5 mm) the same in a temporary arrangement. I understand that you are manufacturing Pallisters/granulator for the sand dust & fine. We would therefore like to get your technical & commercial offer for a 5 ton /hr. Palletizer/granulator system.

Indian customer wants to produce granules materials with 5 ton per hour. The customer has a glass bottle making company in India. In his factory, there are lots of sand dust and fines wastes, so he wants to turn them into granules with additives like soda ash, sodium nitrite solution, and limestones. With a 5 ton per hour production capacity, the customer wants to make granules with an acre of 1360 square meters(40l*34mh) working space. This Indian customer has his own granulation line. However, in customers fertilizer production line, the rotary drum fertilizer granulator does not work well in his granule line, and its granulation rate is far lower than customers requirements. So, Indian customer want to find a new fertilizer production line solution from us.

Based on Indian customers raw materials and production capacity, the companys engineer team design a 5t/h production line equipped with pan granulator. In the disc pan granulation line, the main machine configurations are as follows:

In the sand dust granulation process, we recommend our disc granulator to our Indian customer. However, this customer fear it cannot make well granulated sand dusts as his required. In views of this, we recommend our customer send his raw materials to our factory for working performance testing.

Since customers trial materials are a bit of more, thus it will be more economic we buy the trial materials for customer and customer just pay for the trail material. This will be more economic and cost efficient on the trial process.
