What Is The Difference Between A Sag Mill And Ball Mill

What Is The Difference Between A Sag Mill And Ball Mill

Rod mills are less common than ball mills for grinding minerals. the rods used in the mill, usually a high-carbon steel, can vary in both the length and the diameter. however, the smaller the rods, the larger is the total surface area and hence, the greater the grinding efficiency.Rod mills are similar with the ball mills xcept 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.

Rod Mills How They Function

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.Rods are placed parallel along the length of the rod mill. rods are 150mm shorter than the mill length. breakage occurs more from cascading than cateracting. the product size distribution is narrower than a ball mill but significantly coarser. most are overflow discharge type. length-to-diameter= 1.4 to 2.3. mill length = 7 meters. rod mill.
