2020-3-3 Coals used for power plants normally have different ash contents, and the breakage of coals by the ball-and-race mill or roller mill is an energy-intensive process. Grinding phenomena in mill of power plants is complex, and it is also not the same with ideal grinding tests in labs. The interaction among various coals would result in changes of grinding behaviors and energy

The 3D model in the saVRee database represents a vertical grinding bowl mill Other grinding mill types include the ball tube mill, hammer mill, ball and race mill, and , roll and ring mill Coal Pulverizer Purpose Irrespective of the machine used to pulverize the coal, all coal pulverizers have a similar purpose
Fineness adjustment is done by changing the speed of rotor. Hot air temperature and flow path through the grinding zones have been designed carefully so that it dries out coal without affecting the throughput. ball race mill can handle moisture up to 15%. Mill can handle high ash abrasive coal. Ash percentage does not decrease the throughput.
