media is signifi catively reduced. Therefore, if the power is kept on target when adding small media, the charge will increase and may cause mill''s overcharging, specially if the charge is already at the trunnion level. One should be careful to reduce the power target when converting a charge from larger to smaller grinding media. Flow rate
Charging a Dry Mill – The general operation of a grinding mill is to have the product impacted between the balls as they tumble. If there are insufficient solids in the mill then the media will strike itself and generate excessive media wear. If too much product then the solid may buffer the impact too much.
