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. It 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.

Ball Mills vs Rod Mills. Ball Mills vs Rod Mills When the mill is rotated without feed or with very fine feed, the rods are in parallel alignment and in contact with one another for their full length. New feed entering at one end of the mill causes the rod charge to spread at that end.
Rod life is maximized of rod length-to-mill diameter is maintained between 1.4 to 1.6. Rods wear unequally with thin rod formed at the feed end and forming an elliptical shape. Rod diameter is
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 1.4 to 1.6.
Jun 01, 2017· The ball and rod mills are similar in appearence, as a large rotating lined cylindrical tube filled with either metal balls or long rods used as the grinding medium. In some cases, they can be used interchangable, but not with a mix of balls and rods. Both ball and rod mills can be operated either wet or dry, and in a batch or a continuiously mode.

AG/SAG mills can accomplish the same size reduction work as two or stages of crushing and screening, a rod mill, and some or all of the work done by a ball mill. All because of the range of mill sizes available, AG/SAG milling extends itself to many applications.
1. Rod Mill and Ball Mill. Rod mills are grinding machine which employ high carbon steel or special steel rods of nearly the same length as that of the drum, in place of steel balls in ball mills.
Quinn offers laboratory batch rod and ball mill grinding units normally used for feed preparation in mineral, chemical, and industrial laboratories. Such preparation can be on a wet or dry basis. The charge range for the rod mill is 500 to 2000 grams and the ball mill 500 to 1500 grams based on 2.7 specific gravity material.
Comparison between Rod Mill and Ball Mill. 2014-01-03. Rod mill is a type of grinding mill whose grinding media is steel bar, while ball mill is steel ball. 1. Rod mill are usually applied to grinding the w-sn ore and rare metal in the reselection or magneticore-dressing plant in order to avoid the damage caused by the over crushing.
The impact can be rock on rock such as in an Autogenous Grinding (AG) mill, rock and a small ball charge (~10%), used in Semi Autogenous Grinding (SAG) mills, balls of various sizes in Ball Mills and less commonly these days, steel rods in Rod Mills.
Ball/Rod mill Literature The Ball/Rod mills are meant for producing fine particle size reduction through attrition and compressive forces at the grain size level. They are the most effective laboratory mills for batch-wise, rapid grinding of medium-hard to very hard samples down to finest particle sizes.
