Generally speaking, the initial ball stone gradation of the ball mill is: 30% for large balls, 40% for medium balls, and 30% for small balls. In practice, it mainly depends on the particle size of the material to be abrasive. The diameter and speed of the ball mill should also be considered properly.

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.

A ball mill is a type of grinder used to combine and grind materials into QDs or nano size using varioussized balls. A planetary ball mill is literally loaded with balls, which is why it is nicknamed a "ball mill."Ball mills like the laboratory ball mill or industrial ball mill work by utilizing the force of the moving balls. They don't require a cutting instrument as a result.

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.
