Therefore, the subsequent treatment and utilization of the solid wastes in the mine field become the problems which need to be solved in mine field exploitation, and the valuable components contained in the solid wastes such as waste rocks, waste residues, tailings and the like generated in metal mines can be sorted and refined, so that the mine field resources can be fully utilized, and the exhaustion speed of the mine field resources is further delayed.

However, the solid waste produced in the mine site is often large in size, and the direct extraction cannot effectively separate and extract the components with useful values in the solid waste, so that the efficiency is low when the solid waste is separated and extracted, and the separation and extraction effects are poor, and the occupied space of the solid waste is large and the difficulty is high due to the fact that the solid waste is large in size, heavy in mass and irregular.

Therefore, there is a need for a crushing device for solid wastes in mines, which can crush the solid wastes into required fragments for separation and extraction, so as to improve the utilization rate of mineral resources and avoid the phenomenon of massive accumulation of the solid wastes in mines.
