How To Configure An Artificial Sand Making Plant?

The equipment configuration of artificial sand making plant includes vibrating feeder, coarse crusher, medium and fine crusher, vibrating screen, sand making machine, belt conveyor. Among them, feeders, vibrating screens and conveyors are auxiliary equipment.

1. Feed

The stones blasted from the mountain are sent to the vibrating feeder through the dump truck. Vibrating feeder has strong adaptability, stable operation and high cost performance. It is a feeding equipment widely used in sand and gravel enterprises. The vibrating feeder can feed the crushing equipment continuously and evenly, effectively prolonging the service life of the equipment. Small volume, light weight, small power, compact structure, convenient installation, low operation cost and low investment cost.

2. Coarse and Fine Crushing

According to different crushing purposes, crushers are divided into coarse crushing and medium fine crushing: coarse crushers can process large stones to medium particle size at one time; The medium and fine crusher is mainly used to further crush and reshape the coarse crushed stone to meet the high standard requirements of construction projects for stone. The vibrating feeder evenly sends the stones to the jaw crusher, and the broken stones from the jaw are broken for the first crushing, that is, coarse crushing. The stones broken from the jaw are then transported to the cone crusher or impact crusher through the belt conveyor for secondary crushing, that is, fine crushing.

3. Sand Making and Screening

The finely crushed materials are sent to the sand making machine by belt conveyor for fine crushing, and the finely crushed materials are screened out by vibrating screen.

The general production line can be completed by the above three steps, but for those with strict requirements on the powder content of sand, a sand washer can be added after fine crushing and screening. Circular vibrating screen and linear vibrating screen are common in sand production line. Belt conveyor is the hub of sand production line. It has the advantages of low kinetic energy consumption, high production efficiency, large conveying capacity, flexible use, economy and practicality.

Manufactured Sand

Sand can be divided into natural sand and manufactured sand：

Natural sand: Rock particles with a particle size of less than 5mm, formed by natural conditions (mainly weathering of rocks), are called natural sand.

Manufactured sand：rock, mine tailings or industrial waste slag particles with particle size less than 4.7MM, which are made by mechanical crushing and screening after soil removal treatment, but soft and weathered particles are not included.

Advantages Of Manufactured Sand

1. The raw material of manufactured sand is fixed and produced after being broken by special crushing equipment. The mechanized production mode ensures the quality of manufactured sand is stable, adjustable and controllable, and can adjust the relevant parameters such as particle size distribution and fineness according to the needs of the project, which has better engineering applicability than river sand.

2. The surface of river sand is usually smooth after being scoured by water flow, while the manufactured sand has many sections and rough surface, so the machine-made sand particles can better combine with cementitious materials such as cement.

3. The raw materials of manufactured sand sand can come from some solid wastes. At the same time, in urban planning and construction, a large number of construction waste can be broken by mobile crusher to produce and process recycled aggregate, which not only solves the problem of environmental pollution, but also improves the utilization rate of natural resources.

4. During the period of shortage of river sand resources and rapid rise of raw material prices, the production cost of concrete enterprises can be reduced and the impact on the engineering field can be reduced.

In the mining industry, there are nearly 200 kinds of stones can be used to produce manufactured sand, including solid wastes such as tailings, construction waste, coal gangue, etc. Here is an introduction to common manufactured sand materials and corresponding sand making equipment.

River pebble, granite, basalt, limestone, iron ore, etc.

These stones are all ideal materials in for building. They are hard in texture and can be used as raw materials in sand making production. For example, manufactured sand made of basalt can be mixed with concrete, which can reduce the weight of concrete, and also has the functions of sound insulation and heat insulation. It is a good aggregate for lightweight high-rise building concrete. The manufactured sand produced from river pebbles is often used for road paving and house construction. The stone powder produced in the production of machine-made sand from granite and limestone can also be reused.

2. Sandstone, quartz sandstone, etc.

These stones are mainly composed of feldspar and quartz, which belongs to sedimentary rock. They are good raw material for manufactured sand in terms of grain shape and strength, which can reach or even be better than natural sand. In addition, manufactured sand produced by sandstone also has the advantages of non-weathering, non-melting, sound absorption, and moisture-proof, and it is also a good building and decoration material.

When we use sandstone to crush into construction sand, it needs to go through the production process of crushing, sand making, screening, etc. The whole crushing plant needs to be reasonably matched to achieve low investment and high efficiency. According to the characteristics of sandstone, sandstone is suitable for the following equipment.

3. Tailings, construction waste, coal gangue, etc.

These stones belong to industrial solid waste. But with the advance of sand making process, these wastes are also "treasures", especially construction waste. In recent years, construction waste treatment is a very popular field in aggregates industry, and it has been sought after by a large number of investors. Construction wastes contains lot of crushed stones, concrete blocks, bricks and tiles, which can be crushed and made into new aggregates, and then used in highways and construction.

Using these industrial wastes to make manufactured sand can not only save costs and get high profits, but contribute to waste recycling.

4 Main Types Of Sand Making Machine On The Market

With the development of science and technology and the upgrading of technology, mining machinery is becoming more and more strict in the selection of crushing equipment. In the continuous research and development, transformation and upgrading, different types of sand making machines have appeared one after another. Here are the introductions of 4 main types of sand making machine on the market.

1. Compound Sand Making Machine

It is a traditional and classic type of vertical sand making machine with no grid section design and a very high sand output ratio. Compound sand making machine is mainly suitable for processing limestone, coal and other raw materials with a compressive strength below 140 MPa and humidity under 15%. A single sand making machine can produce sand, which is suitable for small scaled production plant.

2. Double Roller Sand Making Machine

In the working process of double roller sand making machine, the two rollers squeeze each other to process raw materials. And the rollers adopt highly wear-resistant materials, which can process raw materials with high hardness. Whether used for crushing or sand making, double roller sand making machine is very popular among sand and gravel production companies with small or medium scaled because of the low price.

3. Vertical Shaft Impact Crusher

It can be transferred flexibly and has high production efficiency, suitable for factories where the material distribution is relatively wide or the environmental protection situation is very severe.

Sand Making Machine Working Principle & Wear-Resistant Parts

In artificial sand making industry, vertical shaft impact crusher, also known as sand making machine, is widely used as the main sand making equipment. There are two kinds of crushing methods of sand making machine: “rock on rock” and “rock on iron”. But, many people don’t know the differences of these two crushing methods very clearly. In this article, we mainly introduce the 2 crushing methods of sand making machine and their comparison.

Comparison Of Applicable Situations

Generally, “rock on rock” crushing method is used for shaping and “rock on iron” crushing method is used for sand making.

The “rock on rock” crushing method is suitable for crushing abrasive materials with medium hardness and above, such as basalt etc. During the crushing process, materials injected from the impeller impacts the material liner and do not directly contact the metal components of sand making machine, reducing iron consumption and thus reducing maintenance time. The shape of the finished products is good under the crushing method of "rock on rock".

The “rock on iron” crushing method is suitable for crushing abrasive materials with medium hardness and below, such as limestone etc. Under the “rock on iron” crushing method, sand making machine has high efficiency.

How Is Sand Processed - Artificial Sand Technology

Compared with natural sand stone, artificial sand stone is widely used for its advantages of rich material sources, little seasonal impact on processing, good grain shape and grading of finished materials, enhanced concrete strength and reduced cement consumption.

In the design of artificial sand and stone system, sand making technology is the key. How to choose the right production technology to ensure the reliable operation, advanced technology and reasonable economy of the processing system is still an important problem in the design of the artificial sandstone processing system. This article introduces three kinds of sand making processes which are widely used at present.

1. Technology Of Rod Grinding Machine-Made Sand

The particle size distribution of artificial sand rolled by rod mill has a certain rule, that is, one kind of fineness modulus has only one kind of particle size gradation. Therefore, in the production of artificial sand, it is necessary to control the stability of fineness modulus, and the grading of its particle size does not need to be classified.

2. Technology Of Vertical Shaft Impact Crusher Sand

The high-speed rotating materials are used to break each other by themselves and friction between materials.

The vertical shaft impact crusher can be divided into "stone striking iron" and "stone striking stone" according to its working mode: the sand making machine impeller rotates at a high speed driven by the motor, throwing materials out of the impeller flow channel and hitting them on the reaction plate. The vertical shaft impact crusher equipped with the reaction plate is called "stone striking iron"; if the reaction plate is not installed, the materials thrown out by the impeller of the crusher will be hit and formed naturally This kind of situation is called "stone striking". The sand production rate of "stone and iron" is higher than that of "stone and stone".

3. Combined Sand Making Technology

Through the analysis of the sand production law and technological characteristics of rod mill and vertical shaft breaking, it can be found that the sand production rate, fineness modulus, powder content and product grading are all highly complementary. Therefore, the combination of rod mill and vertical shaft breaking can make up for their shortcomings.
