The operating principle of the ball mill

The operating principle of the ball mill consists of following steps. In a continuously operating ball 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.Ball mills: design and operating principle - Strommashina,Ball mill design is rather simple. This grinding equipment is a drum filled with metal or cast iron balls (grinding media). It is used mostly for production of bulk construction materials, paints, pyrotechnical devices, ceramics and in other industries. The ball mill patent was sealed more than 180 years ago.
