Dump rock is mainly construction waste, scraps, tailings and so on. It can be produced by special crushing, sand making and other equipment. Now, the wide application of these dump rock crusher machine reduces the pollution caused by waste, and alleviates the pressure brought by the shortage of stone materials in infrastructure projects, provides a boost for sustainable development, and successfully turns waste into treasure. The new value, coupled with low production costs, high profits and quick returns, makes investment prospects very promising.
Three steps of dump rock crushing:
The first step: After coarse crushing and screening, dump rock is divided into 20-40mm coarse aggregate, which can be used for laying roads, railways, bridges, water conservancy and hydropower.
The second step: Secondary crushing, screening into 10-20mm medium fine aggregate, used for building mixed stone, pile foundation filling, and roadbed raw materials, etc.
The third step: After the sump rock is broken in two steps, sand making and screening are carried out to make 1-5 mm fine aggregate, which is used for machine-made sand.
