Can gangue be used as raw material for sand making

With the gradual reduction of natural sand and gravel resources, as well as the rapid development of construction and other industries, the mechanism of sand quickly occupied the market. The raw materials for the production of mechanism sand are mostly ore resources in nature, as well as construction waste. Construction waste sand can meet the needs of environmental protection, but also provide the market with low-priced finished sand and gravel. So as raw coal waste gangue can be used as raw materials for sand production?

Coal gangue is in the process of coal mining and coal washing solid waste, hardness is higher than coal, stable performance, with good thermal insulation properties, good adhesion, and the gangue has a good compressive capacity, compressive range of 300-4700mpa, so it can be used for sand making. And the gangue sand and gravel finished product quality is excellent, has a wide range of applications.

Gangue is a hardness of about 3 materials, so it is easy to crushing processing, sand and gravel finished products can be used in the production of concrete lightweight aggregate, gangue bricks and other building materials. And the sand making equipment on the market has the advantages of adjustable particle size and diverse models, so according to the production needs of different industries, you can choose different sand making machine to process gangue.
