Comparison between Rod Mill and Ball Mill

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 2 In the two stage grinding process if it requires grinding the ore from 20-6mm to 1-3mm in the first stage rod

Ball vs Rod vs Roll Mills

11 06 2019The 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

TECHNICAL NOTES 8 GRINDING R P King

These mills exist in a variety of types - rod ball pebble autogenous and semi-autogenous The grinding action is induced by relative motion between the particles of media - the rods balls or pebbles This motion can be characterized as collision with breakage induced primarily by impact or as rolling with breakage induced primarily by crushing and attrition In autogenous grinding machines

Rod Mill

Rod Mill Introduction The Rod Mill manufacturer adopts advanced controllable feeding and discharging technology combined with the actual grinding material with the appropriate grinding body and the traditional surface contact is changed into line contact so that the discharge granularity is more uniform and the output is higher

Rod mills how they function

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 Rod mills accept feed up to about 50 mm (2 in ) and produce a product in the size range of

Optimization of mill performance by using

Optimization of mill performance by using online ball and pulp measurements by B Clermont* and B de Haas* Synopsis Ball mills are usually the largest consumers of energy within a mineral concentrator Comminution is responsible for 50% of the total mineral processing cost In today's global markets expanding mining groups are trying to optimize mill performances Since comminution is

Laboratory Rod Mill

XMB series rod ball mill is an efficient laboratory grinding equipment for wet grinding of ore or other materials Steel balls can be used as grinding medium instead of steel rods In rod grinding operation particle sizes of final product are relatively uniform and ore overgrinding can be eliminated Generally speaking lab rod mill is commonly used as a grinder for mineral feasibility study

Rod Grinder Rod Mill Crushing Mill Grinding Rod Features of Rod Grinding Machine During the grinding process the grinding medium line contacts with the ores Due to selective grinding the granularity of products is more even resulting into less ore grains In coarse grinding bar mills have greater capacity than the ball mills of the same specification Working Principle of Rod Grinding Mill

the Difference of Rod Mill and Ball Mill

Rod mill and ball mill may be only one word difference in the name but in fact there was a striking internal differences Rod mill as the name suggests is to rely on rod bars for the material grinding and wet overflow is a generally used material way Rod mill is generally used as a grinding equipment in the artificial stone sand concentrator chemical plants and power sectors The ball

Ball Mill

The feed to ball mills (dry basis) is typically 75 vol -% ore and 25% steel The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones The cyclones send correct-size material on to flotation and direct oversize material back to the ball mill for further grinding
