For a ball mill, if the reduction ratio becomes less than 3 (target grinding of concentrates), the energy index W i must be multiplied by a given coefficient given by the author''s equation 27 [BON 61b, p. 545].

standard number of reduction ratio of grinding mill. 150 where RRO = optimum reduction ratio for the mill size = 8 . long and tedious and requires a standard set of grinding conditions; mill size, ball .

In general, ball mills can be operated either wet or dry and are capable of producing products in the order of 100 μm. This represents reduction ratios of as great as 100. Very large tonnages can be ground with these ball mills because they are very effective material handling devices. Ball mills are rated by power rather than capacity.

Extensively field tested and proven in harsh cement applications, our mill drive gearboxes cover all grinding applications up to 10 MW per drive and we have single, double and triple reduction gearing available depending on the required ratio and motor speed.

Ball mill. A typical type of fine grinder is the ball 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%.

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