GRINDING MACHINE ITRODUCTION.

Ball mill is suitable for grinding all kinds of ores and other materials, no matter wet grinding or dry grinding. Besides, it is the key equipment that pulverizes the materials after they are crushed and it is widely used in the manufacturing industries, such as cement, silicate, new building materials, refractory materials and fertilizers.

GRINDING MACHINE WORKING PRINCIPLE.

The main part of cylindrical energy saving grid 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 grinded 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 grinded material is discharged from the cylinder outlet. In wet grinding, material is taken out; in dry grinding, the material is taken out by air. 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.

GRINDING MACHINE APPLICATION.

Ball mill is mainly used to grind materials in mineral, cement, refractory, chemical industry, etc. Ball mill has dry and wet ways. When wet ball mill works, certain water and other liquid will be added into materials to increase flow ability of materials, so the capacity is increased. When dry ball mill works, capacity is affected because material flow ability is reduced, so absorbing wind device is needed on the outlet of ball mill, and then negative pressure is formed in the ball mill to increase flow ability of material, so the capacity is increased.
