The ball mill''s low pressure oil system pumps oil from the reservoir through a filter assembly to clean the oil before the flow is sent to the trunnion bearings. During startup, the oil is also pumped to the high pressure pump. Dual cartridge filters, connected in parallel, continually clean the oil.
May 22, 2019· The ball mill consists of a metal cylinder and a ball. The working principle is that when the cylinder is rotated, the grinding body (ball) and the object to be polished (material) installed in the cylinder are rotated by the cylinder under the action of friction and centrifugal force.
