"Coarsening" of ball mill is an abnormal phenomenon that the fineness of grinding products is significantly coarser and difficult to control. It generally occurs in double bin open circuit tube mill with small length diameter ratio. Coarsening of the ball mill will increase the energy consumption of the ball mill, cause waste, and large particle size will also affect the subsequent sorting.
