Ball mill is widely used for milling various kinds of ores or rocks in metal and non-metal mining and building material industry.The main bearing of the ball mill with the shell diameter 900-2100mm is spherical liner bearing; for the shell diameter 2700mm, the main bearing is completely closed self-aligning 120bearing with strong alloy of high lead and low tin with low hardness, underneath laid with cooling copper piping full of water the bearing is of static pressure structure with high and low pressure united oil lubricating system.

1.The quartz ball mill uses a grooved ring-shaped lining plate, which increases the contact surface of grinding balls and ore, strengthens the grinding effect, reduces energy consumption.
Because of the different structure, the occupied area of grinding machine and ball mill is obviously different.
The ball mill is suitable for all grindable materials.For example, metal ores can be processed by ball mill including gold ore, copper ore, iron ore and chromium ore, etc., and non-metallic ores including cement clinker, slag, quartz sand, feldspar and limestone and so on.

1.Low investment costthis mill itself can crush, dry, grinding, classifying, so the system is simple, and occupation area is about 50% of ball mill system.In addition, it can be installed outside, so it will reduce a large number of investment costs.
Planetary ball mill is designed for rapid fine crushing of soft, hard, brittle and fibrous material to end fineness <1um.It can not only perform mixing and grinding but also meet the requirements of colloid grinding.In addition, its giant energy input can meet the technical requirements of preparing alloy with the mechanical method.
Influenced by the material hardness and size as well as the discharge size requirement, the production capacity of the grinding machine and ball mill is different.
Second.Install the barrel of ceramic ball mill.According to the specific conditions, the pre-assembled whole simplified parts can be directly installed or installed in several parts.Check and adjust the center line of the journal and ceramic ball mill.
Rod mills are very similar to ball mills, except they use long rods for grinding media.The rods grind the ore by tumbling within the the mill.To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6.More.
