The ball mill for the installation of horizontal rotating cylinder, outer edge of which lies Gear, two warehouses, lattice-type ball mill. Feed materials from the device into the compound empty-axis spiral uniform access to the first Mill Wharf, the warehouses have stepped liner or corrugated liner, the contents of different specifications Ball, the centrifugal force will have a rotating cylinder ball to a certain altitude sets, and have severe impact on materials and grinding role. Materials in the first positions to grinding, single-layer at the plate in the second warehouse stores, the warehouses incalculable-liner with a ball, will further polishing materials. Discharge through the grate of powder from plate to complete grinding operations.

Grinding operation is a further processing for the crushed product, which achieves monomer dissociation of objective mineral and provides qualified products for separating operation. Grinding operation is an essential processing in most of beneficiation plants, and also the last processing before separating operation. Grinding is a high energy and material consumption operation, so the quality have a straight effect on the target of separating operation. Actually, the capacity of beneficiation plant depends on the capacity of grinding, therefore grinding is the most important operation before mineral separation. Generally, the main workshop of one plant is grinding house, which also illustrates the importance of the grinding operation.



There are some quantity index in the overview of the working principles of ball mill:



Capacity: or called hourly capacity per mill, ore quantity that a ball mill can produce per hour under a certain ore size and product granularity, in t/h per device.



Mill utilization rate (In terms of the original ore): ore quantity that a ball mill can produce per hour and per cubic meter under a certain ore size and product granularity ,in t/(m3·h).



The medium in the cylinder will drop and rotate, which generate power of impact and grinding, and then achieve the crushing of the ore. That is the working principles of ball mill. The movement of steel ball is related to the fill rete. The more the rate is, the less likely that the ball can slide along the inner side of cylinder. On the contrary, the more likely of slipping phenomenon. When the fill rate drop, the steel ball will beat near the bottom of cylinder. Both the high and low fill rate cannot make the ball mill to meet the design requirements. Ball mill produced by Xinhai can meet all you demand. Choice xinhai, choice high quality.

A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering.



A ball mill works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.



A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the shell may be either horizontal or at a small angle to the horizontal. It is partially filled with balls. The grinding media is the balls, which may be made of steel (chrome steel), stainless steel or rubber. The inner surface of the cylindrical shell is usually lined with an abrasion-resistant material such as manganese steel or rubber. Less wear takes place in rubber lined mills, such as the Sepro tyre drive Grinding Mill. The length of the mill is approximately equal to its diameter.

The mill has metal balls of various sizes which fall onto the material to be crushed. The balls and material are housed in a horizontal cylinder which is slowly rotated allowing the balls to move over and fall onto the product. The finished product is sieved to remove larger particles which are then returned to the mill in the next raw material load. The ball mill is not good for making gunpowder or any other product which may be unstable and susceptible to shock.
