the operating principle of the ball mill

the operating principle of the ball mill

Theoperating principle ofthe ball millconsists of following steps. In a continuously operatingball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls. Then, discharge of ground material performed

Theball millingprocess is carried out for approximately 100–150 h to obtain uniform-sized fine powder. In high-energyball milling, vacuum or a specific gaseous atmosphere is maintained inside the chamber. High-energy mills are classified into attritionballmills, planetaryballmills, vibratingballmills, and low-energy tumbling mills
