The material on the screen is small pieces of construction waste and ore, with a particle size of 10 < ≤100mm; the other route passes through the primary crushing of the mine and is directly transported to the 3000t concrete transfer warehouse through the transfer belt;

[0045] Primary crushing: the materials on the bars are evenly dropped into the jaw crusher for crushing. The particle size of the materials after crushing is less than 300mm.

[0046] Magnetic separation: After crushing, the materials on the screen are combined and transported, and the iron metals are recovered by the iron remover. The separated metals are piled up and sold in batches after reaching a certain amount;
