Live ChatBall Mill. SBM ball mill is one of the new high efficient grinding machine,which is widely used in the in various types of stone grinding plant, ore benefication, electricity, cement and chemical industries.This new type ball mill with high comminution ratio, it can carry out dry or wet pulverizing and can meet demand for sustainable large scale production.

Live ChatBall mills tumble iron or steel balls with the ore. The balls are initially 510 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol. % ore and 25% steel. The ball mill is operated in closed circuit with a particle size measurement device and size control cyclones.

Live ChatThe efficiency of size reduction is influenced by a number of variables including the mill speed, ball size, filling rate, feed size distribution, pulp density, coal rank, the mode of grinding (wet or dry), material hardness, and dissemination features [, , , , , , , , ]. The mode of grinding, wet or dry, has significant differences in grinding

Live ChatIf a ball mill uses water during grinding, it is a wet mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills. Ball mills may be primary or secondary grinders. Primary grinders are fed from crushers such as a
