For the mill equipped with spring load system, the grinding force is overloaded at reduced mill load. This will result in additional wear on roller and table segments and will produce excessive mill vibration. While at high mill load operation, the grinding force is insufficient to meet the requirement for mill load increase. o 180 160 140 120 100
