The particle size range of the grinding mill is wide, and the particle size can reach 2500 mesh. 2. Hardness of grinding materials. The harder the material is, the more difficult it is for the grinding mill to grind, and the more severe the wear of the equipment is. Raymond grinding speed is slow, of course, Raymond grinding capacity is small.

Grinding is most often performed with an ore/water slurry, which reduces particulate matter (PM) emissions to negligible levels. When dry grinding processes are used, PM emissions can be considerable. After final size reduction, the beneficiation of the ore increases the concentration of valuable minerals by separating them from the matrix rock.
