Operation Principle of Iron Ore Ball Mill - Xinhai

The diameter of steel balls near the feed end is bigger than near the discharge end. The impact of steel balls downward movement can help ball mill to complete the mill work. Ball mill relies on the motor and decelerator to drive small gear, and the cylinder is drove by the mesh of pinion and ring gear.

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 ...

Ball Mill Critical Speed - Mineral Processing & Metallurgy

A Ball Mill Critical Speed (actually ball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at the mill shell's inside surface and no balls will fall from its position onto the shell. The imagery below helps explain what goes on inside a mill as speed varies.
