design and analysis of pulvased ball mill machine

Several types of ball mills exist They differ to an extent in their operating principle They also differ in their maximum capacity of the milling vessel ranging from 0010 liters for planetary ball mills mixer mills or vibration ball mills to several 100 liters for horizontal rolling ball mills
