The planetary ball mill supports both dry and wet grinding, but wet grinding is higher in efficiency and particle size than dry grinding. In the grinding process, the addition of grinding aids or dispersants reduces the agglomeration and re-fusion of materials; the amount of grinding aids and dispersants should also be paid attention to.
Wet milling with IKA's inline machines is a safe and efficient alternative to dry grinding. Dry grinding creates a lot of dust which causes the need for proper filtering systems.

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.
