The project of crushing bluestone into machine-made sand by pulverizer conforms to the concept of national sustainable development and has received strong support from relevant departments. Bluestone is a good raw material for producing sand aggregate. It has the advantages of moderate hardness, wide distribution, convenient material acquisition, wear resistance, weather resistance, no radiation, easy crushing, high sand formation rate, beautiful particle shape, uniform particle size, reasonable gradation, environmental protection and large market demand.
With the development of economy, the construction of cities can not be separated from the help of sand and gravel aggregate, especially at present, the urbanization process in China is accelerating, and the market demand for sand and gravel aggregate is increasing. Natural sand and gravel can no longer meet the market demand, and the price of sand and gravel is rising at a speed visible to the naked eye. There is only one way out for machine-made sand.
