Introduction Of Ball Mill
Ball mill, a pulverizing machine consisting of a rotating drum which contains pebbles or metal balls as the grinding medium, can grind ores and other materials typically to 20 mesh or finer in a variety of applications, both in open or closed circuits.
Applied materials Of Ball Mill
Applied materials: cement, silicate, new-type building material, refractory material, ore dressing of ferrous metal and non-ferrous metal, glass ceramics, etc.
Ball mills are widely used in cement, silicate products, new building materials, refractory materials, fertilizers, black and non-ferrous metal dressings, and glass ceramics. Dry or wet grinding of various ores and other materials.
Working Principle of Ball Mill
Add balls into the ball drum to approximately 33%. The figure is not fixed, as long as it is within the range of 30%-45%. As the ball mill rotates, the balls ‘stick’ to the inner surface of the ball drum due to the centrifugal force and are lifted on the rising side. At a certain angle, balls cascade down to the centerline of the ball mill because gravity overcomes the centrifugal force. And the ore is reduced to the required size by impact (balls impacting with the ore) and attrition (ore rubbing against other bits of ore and the milling balls).
Advantages of Ball Mill
Energy-saving:
High grinding efficiency:
Good operating conditions:
