BALL MILL Principle Th ball mill work on the principle of impact between the rapidly moving ball the powder materiel, both enclose in a hollow cylinder. At low speed the ball role over each other attrition will be predominant mode of action. Thus, in boll mill impact or attrition or both are responsible for size reduction.

The Ball Mill operates by rotating a cylinder with grinding balls like steel, CI, ceramic and pebble balls as grinding media. Material fed through the mill is crushed by impact and grounded by attrition between the balls and also the internal cascading effect reduces the material in to a ne powder. Ball Mills usually have liners inside which are

The attritor, or stirred ball mill, is a grinding mill containing internally agitated media. There are quite a few types of attritors; they can be categorized as dry grind, wet grind, regular speed (to 400 rpm) and high speed (4001,800 rpm) attritors. A useful and simple equation describing the grinding momentum is M x V (mass x velocity ...
