Ball mill is broken and ground into a pulverized coal machinery, it is important pulverized coal boiler auxiliary equipment. Coal grinding process is broken and the surface area of coal has been growing process. To add a new surface area, must overcome the binding force between the solid molecules, and thus need to consume energy. Coal grinding mill was made of coal, mainly through the crush, break and crush three ways. Process in which crushed the energy consumption of most provinces. Pulverization process of the most expensive energy. Various mill in the milling process are both the above two or three ways, but mainly depends on what kind of mill type.
Many types of steel ball, grinding coal at the speed of the working parts can be divided into three types, namely low-speed mill, pulverizers and high-speed mill.
Ball mill use and the use of overview:
Ball is the material to be broken, and then to smash the key equipment. Ball mill is widely used in cement, silicate products, new building materials, refractory materials, fertilizer, ferrous and nonferrous metal and glass ceramics and other mineral production industries of all kinds of ores and other grind-able materials can be dry or wet grinding.
Ball Mill Work Description:
This machine is a horizontal cylinder rotating mechanism, outer gear, the two positions, lattice-type ball mill. Material from the feed device into the compound by the air shaft into the mill screw evenly the first warehouse, the warehouse has ladder liner or corrugated liner, built with different specifications steel ball, rotating cylinder produces centrifugal force to the ball a certain height After the fall, have severe impact on the material and abrasive. To coarse grinding of materials in the first position, after single-layer diaphragm plate into the second position, the positions are lined with flat lining, the steel ball, the material to further grinding. Powder discharged through the discharge grate plate to complete the grinding operation.
Overview of structural characteristics of ball mill:
Ball Mill from the feeding part, discharging the Ministry of Rotary Department, the Ministry of transmission (reducer, small transmission gear, motor, electric control), and other major components. Cast steel hollow shaft, lined with removable, rotary gear hobbing by casting process, the body inlaid cylinder liner wear, has good wear resistance. The machine running smoothly, work reliably.
According to materials and methods of discharge, optional dry ball mill and wet lattice-type ball mill.
