Ball grinding process is a grinding method of crushing ore with ball-shaped grinding medium in the grinding mill. In the ball grinding process, because the steel ball has 360° free rotation, it is suitable for falling motion and throwing motion. ... The former is widely used in coal-fired power plants and cement industry, and the latter is ...
This step involves the material being retained inside the mill for a specific time (with or without grinding balls) which is calculated by applying Bond's work index to the process calculation. This index takes into account the material ore hardness and feed size, mill speed, material recirculation, desired fineness, etc.
In addition, the entire coal processing plant must be considered to make the coal crushing plant compatible with the equipment of the screening plant, powder grinding plant, and coal wash plant, such as vibrating screens, coal mills, rotary dryers, etc. The following are commonly used equipment combinations in the coal crushing plants:
