Ball mill. A typical type of fine grinder is the ball mill.A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.
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 start-up, the oil is also pumped to the high pressure pump. Dual cartridge filters, connected in parallel, continually clean the oil.
