Ball Mill Breakage Efficiency. Consider a ball mill circuit processing material of a given feed size and at a given throughput rate to a target product size, the latter which once again distinguishes the "fines" from the "coarse" material. The production rate of fines or new product size material can be calculated from the circuit feed ...

Generally ball mills are utilized after an initial material crushing or grinding has occurred. Thus, a disadvantage of the ball mill is that the feed size must already be small. Table 2 outlines some typical ball diameters found in ball mills dependent on the staging or purpose of the mill. Table 1 Ball mill feed and product sizes (Callow ...

It may be a closed or open circuit grinding systems. In recent days, the Ball mill grinding systems are used with the Roller press and it is developing very fastly. The primary grinding is done by the Roller press and finish grinding takes place in Ball mill. Because of this, we can increase the Ball mill capacity as well as the Cement production.

Ball mills are applicable only in the primary milling. The milling efficiency and the related energy demand render impossible the use of ball mills for fine milling [15,16]. The number and the type of internal mill components (, the type of the inner lining, the type and number of the diaphragms) are important

There are two "inputs" to a ball mill circuit: the ore fed to the circuit and the power delivered by the grinding mill. A ball mill circuit has two "efficiencies": that of the ball mill grinding environment* and that of the classification system*. A ball mill circuit has two efficiencies because it has two main functions:
