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, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at to
The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls.

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 50% of the mill volume and its size depends on the feed and mill size.
where an approximate figure for the constant is for rod mills, for overflow ball or pebble mills and for grate discharge ball or pebble mills. ç is specific gravity of grinding media (for rods or balls normally ) q is the charge volume in fraction of mill volume (40 % = ) nc is the mill speed in fraction of critical speed
Overflow Versus Grate Discharge Ball Mills: An Experimental Investigation It has been widely accepted to go for grate discharge ball milling when a coarse product is preferred or to avoid production of extreme fines, but overflow discharge mills are preferred for their simplicity of design .
Discharge of pebbles, finer rock, ball scats and slurry from mills and its flow through trommels, and into other processing operations has strong impacts on overflow ball mill performance.
Ball Mill Grade Discharge Design Overflow VS Grate Discharge Ball or Mill Why Retrofit. Overflow VS Grate Discharge Ball or Mill Independent tests have shown that regardless of mill shape or design, the discharge product of an overflow mill will be . Ball Mills .
The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum ''chunk size'', product size as P80 and maximum and finally the type of circuit open/closed ...
The choice of mill design depends on the particle size distribution in the feed and in the product wanted. Often the grinding is more economic when executed in a primary step, followed by a secondary step, giving a fine size product. ... ball mills, grate discharge 1/1200 ball mills, overflow type 1/1470 pebble mills .
