The ball mill can efficiently and finely grind various materials with different hardness and abrasion properties, including metallic ores, non-metallic ores, cement clinker, etc.; It has a highly automated control system, including automatic start and stop, adjustment of grinding speed and addition of grinding media to improve the convenience of operation;
Given that mills are charged to the target ball charge with reasonably sized media, and the feed to the ball-mill circuit is not so coarse as to cause constant scatting, the key to efficient ball-mill circuit operation is efficient classifier operation. The standard classifier for ball-mill circuits is the hydrocyclone.
Ore processing is a 24 hour operation. Ore is stockpiled at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added to raise its pH. Following crushing through a jaw crusher, the ore is fed into the semi autogenous grinding (SAG) mill along with water and steel balls.
