Natural sand can not get a wide circulation under normal circumstances, so artificial sand has become a great resource in construction industry.

With advancement of technology and rapid economic development,industry of sand making machine is rapidly rising. Artificial sand manufacturing unit,river gravel sand manufacturing unit and river pebbles sand manufacturing unit shines for many investors.There is a great room for development in this industry.So what are the raw materials of artificial sand?

1.River pebbles 
River pebbles is also a quality raw material of artificial sand in strength, grain type, color terms.It is the best choice to replace natural sand.

2.Quartz sandstone 
Quartz sandstone is high quality raw materials, both in intensity or grain type which can achieve even better than natural sand.

3.Limestone 
Limestone can be treated as sand and gravel materials at the same time in artificial sand production line.It's powder can be reused.

4.Basalt 
Artificial sand made from Basalt is mixed in concrete, can reduce the weight of the concrete.But the concrete has strong,soundproof,insulated and other features, is a good lightweight concrete aggregate of high-rise building.

5.Sandstone 
High quartz content,It is widely used in the gravel production line.It can solve the problem of powder in the production.

6.Granite 
High quartz content,low sulfur content.Granite is a quality raw materials of artificial sand.

In fact,there are many other raw materials of artificial sand.All above are the most common types in artificial sand production line.
