In the present study, the effect of grinding media shape on breakage parameters was investigated.Balls and cylpebs were used as the grinding media.It was observed that the grinding of quartz obeyed firstorder breakage kinetics in the case of balls and cylpebs.Higher breakage rates were noted with cylpebs than with balls.Furthermore, it was found that the primary breakage distribution.Get Latest Price

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 consumption.
