Recommendation of ball mill and rod mill ball mill and rod mill are suitable for different materials 1 selection by materials hardness ball mill has a strong adaptation of material and it is suitable for grinding hard materials such as slag iron ore copper ore etc rod mill is suitable for grinding brittle material such as rare metals

Jeanpaul duroudier in size reduction of divided solids 2016 374 performance rod mills are used in an open circuit between crushing and the ball mill they often operate in wet and where the pulp contains up to 50 solid by mass this machine is equally very applicable to dry where it could take a feed that has achieved 6 moisture
In addition the cylinder speed of the rod mill is lower than that of the ball mill so the grinding medium works in the cascading state 2 discharging way of ball mill and rod mill the ball mill is commonly divided into grid type ball mill and overflow type ball mill named by the different discharging structure
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 14 to 16 rod mills accept feed up to about 50 mm
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
Parameters of rod mill from uganda to that of the ball mill test as follows it is common to observe a difference between the rod mill and ball mill values for a given ore type these differences may be caused by a variation in ore hardness by size 125mm for rwi and 335mm for bwi andor grain the ball mill is a tumbling mill that uses steel
