Steel balls have a SG of and have an average weight/volume of 40 pounds/gallon. Higher density grinding media generally results in faster grinding in a ball mill. An optimum grinding charge for a ball mill may be experimentally determined, however generally the range is from 20% to 50% of the mill volume, or to the center line.

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 3045%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.

A pharmaceutical ball mill is a type of grinder used to grind and blend materials while manufacturing various dosage forms. The size reduction is done by impact as the balls drop from near the top of the shell. Ball mills are used primarily for singlestage fine grinding, regrinding, and as the second stage in twostage grinding circuits.

A ball mill is a cylindrical device that rotates around its axis, partially filled with the material to be ground plus the grinding medium (usually ceramic balls, flint pebbles, or stainless steel balls). As the mill rotates, the grinding media crushes and grinds the material against the inner surface of the mill chamber, creating a fine powder.
