Mining Rock Ore Grinding Ball Mill Powder Grinding Machine

Short Description:

The ball mill is suitable in the powder rubs each kind of ore and other materials, the balll mill is widely used in the dressing, professions, building materials and chemical industry and so on. It is divided into two rubbing way-the dry and the wet .There are two kinds of ball mill, grate type and overfall type due to different ways of discharging material. The ball mill is a key equipment to grind the crushed materials after the material were broken , and carrying on the smashing again. and the ball mill is widely used in powder-making production line including cement, silicate, new-type building material, refractory material, fertilizer, ore dressing of ferrous metal and non-ferrous metal, glass ceramics, etc,the ball mill carries on the dry type or the wet powder to each kind of ore and other grindability material rubs.

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.

Work Principle

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.
