Ball mills: design and operating principle - Strommashina

Design and operating principle A ball mill is a hollow drum rotating around its horizontal axis. It is filled with grinding balls (impact elements). As a result of rotation, balls on the internal drum surface lift and then fall down under the gravity action. The source material is permanently fed through one of spigots.
