Common reasons for the high ball mill grinding equipments causes depletion and power consumption due to wear ordinary ball surface and core part of the difference between the larger, its diameter is reduced uneven wear of the process, on the one hand will lead balls level Hotels prone to large deviation, resulting in poor coal fineness or reduce output; on the other hand will result in the formation of failure of the ball, affect output or leaving the ball because the ball high up the load increases. Second, because of the increased failure of the ball, while the broken ball rate will increase, resulting in ball consumption and electricity consumption rises. Once again, ordinary wear faster ball for reasons, mostly forced to use a larger ball diameter, ball diameter of 30mm or more accounted for up to 70 percent as much as the point of causing balls of the same weight or effect of reducing the area, making the ball is not efficient. And The study showed that 25 ~ 30mm diameter ball enough coal mill will be made of pulverized coal power plants.

Ball is the material after being broken, and then to smash the key equipment. It is widely used in cement, silicate products, new building materials, refractory materials, fertilizer, black and non-ferrous metals and glass ceramics and other production industries of all kinds of ores and other grind-able materials can be dry or wet grinding.
Dry ball mill and wet ball mill structures are made by feeding part, discharging part, turning part and driving part (reducer, small transmission gear, motors, electrical control) and other major components.
The difference dry ball mill and wet mill structure at: dry ball-shaped spout is straight, there is also an induced draft system, dust emission. Wet ball mill is a horn-shaped spout, built-in screw device, convenient discharged material. Most on the market for wet ball mill, wet grate ball mill grinding fineness, good...
