Overview of Ball mill
Ball mill is the key equipment used in grinding of materials after being primarily crushed, which is widely used in the manufacturing industry of cement, silicate product, new building material, refractory, fertilizer, mineral processing of black and non-ferrous metals as well as glass ceramic for the grinding of all kinds of ores and other grindable materials. There are two ways of grinding: the dry way and the wet way.
Features of Ball Mill
According to the way of materials and discharging, ball mill can be divided into dry type ball mill and wet type lattice ball mill.
Ball mill is mainly made up of feeding part, discharging part, rotary part and driving part, including reducer, small drive gear, electrical machine and electronic control. The hollow shaft adopts steel casting, and its inner lining is detachable and changeable while the rotary rack wheel uses casting gear hobbing and there is a wear-resisting lining board inside the cylinder with good abrasion performance. This machine is featured with stable operation and reliable performance.
Working principle
This machine is a horizontal cylinder rotating device. It is equipped with drive gear which drives the cylinder for rotation in the working process outside the cylinder. Materials go into the first cabin of the grinding machine spirally and evenly through the feeding hollow shaft from the feeding device, and there are ladder lining boards or ripple lining board inside the first cabin where there are different kinds of steel balls. When the cylinder rotates and produces eccentric force to bring the steel balls to a certain height, the steel balls will fall down to impact and grind the materials. After being coarsely grinded in the first cabin, the materials will go into the secondary cabin where there are flat lining boards through the single-layer partition board. There are steel balls for further grinding the materials in the lining board. Finally the powdery materials will be discharged from the discharging grating bar to complete the powder grinding process.
