ball mill is a type of grinder used to grind and blend materials for use in mineral processes. ball mill works on the principle of impact: size reduction is done by impact as the balls drop from near the top of the shell. rod mills are very similar to ball mills, except they use long rods for grinding media.
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 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 moisture.
