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.
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.
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.
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.
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.
