Crushing Equipment 101
The mining and quarrying industry is one of the largest users of crushing equipment. Raw material is blasted or harvest from deep underground. For these materials to be profitable, they have to go through an extensive material handling system. The material is moved from the mine, fed into a crusher, than screened to separate the particles.Web
