1. Introduction. Compared to conventional steel media, ceramic balls have a lower specific gravity and superior wear resistance [1].Ceramic balls were initially used primarily in the IsaMill because they could provide fast stirring speed while maintaining high kinetic energy (E = mv 2) despite their low specific gravity [2].According to Kwade's stress model [3, 4], which is illustrated in Eqs.

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 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.

Then in ballwear formula (25), T = /K Log10 Da/Db; but from (29), K = Rt/Wt. Then T = /Rt Log10 Da/Db T is 1 day, Wt is the original weight of the ball charge, and Rt is the ball wear for one day. Then Log10 Da/Db = Rt/ are all known, and it is only necessary to solve for Db, the diameter of the balls to be added.

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.
