advantage of using rod mill over ball mill

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. This produces a series of wedge shaped slots tapering toward the discharge end. The tumbling and rolling rods expend most of their crushing force on the ...

Rod Mill - an overview ScienceDirect Topics

As such, when the product is sticky, rod mills are preferred over ball mills. Rod mills have an industrial yield that is less than that of a ball mill, which explains the fact that balls have a much larger grinding surface than rods. The power needed to operate a rod mill could exceed 30% of the power used in a ball mill. When they are worn, rods must not stretch but break in rather small ...

THE ADVANTAGES OF USING A GRINDING SYSTEM

22/11/2017  The rod mill is a grinding system very similar to ball mills, but use steel rods instead of balls as the grinding medium. When they are being operated the ore and the rods tumble within the mill and causes a lot of friction. There is no cascading and therefore the grinding process is much faster compared to the ball mill.

Rod mills, how they function - Mine Engineer.Com

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 ...
