Ball Mill Principle Construction Uses Advantage
The ball mill operates on the principle of impact and attrition In this impact occurs between fast moving balls and the powder material while the attrition mode comes in action when the hollow cylinder rotates on its longitudinal axis All is occurs at low speed and the balls roll over each other.
