The main part of wet ball mill is cylinder with small diameter and large length rotating slowly by the transmission device. The material is fed from the cylinder inlet and ground by the impact of steel ball and ore and self-grinding. Due to the continuously feeding material, the pressure pushes material to the outlet and the ground material is discharged from the cylinder outlet. The grid installed in the outlet of mill is relied for forced discharge. Low pulp surface in cylinder reduces the ore over-grinding, and prevent the steel ball out. Under the same production conditions, production capacity of grid mill is larger than overflow mill’s. Both ends of the cylinder body adopt rolling bearing instead of the sliding bearing, which is more energy-saving.| Type | Rotational speed （r/min） | Balls weight (t) | Feeding size (mm) | Output size (mm) | Capacity (t/h) | Motor power (kw) | Weight (t) |

The ball mill is a key equipment for regrinding. It is widely used for the cement, the silicate product, new type building material, fire-proof material, chemical fertilizer, black and non-ferrous metal, glass, ceramics and etc. Our ball mill can grind ore or other materials that can be grinded either by wet process or by dry process. The ball mill is suitable for the beneficiation and grinding of fly ash, limestone, quartz sand, aluminium powder, coal powder, steel slag, ore, potassium feldspar, iron ore, iron slag, aluminium slag, silicon carbide, alumina, coal gangue and other materials.
