Compared to 4" media, a larger 5" ball will: Coarsen the mill discharge size. Increase potential for liner damage/higher wear rate. Provide a lower number of impact breakage events due to the lower number of balls. Provide higher energy impact breakage events. In a way, the media size should be selected based on feed size and grate opening.

Ball mill： Ball mills are the most widely used one. Rod mill： The rod mill has the highest efficiency when the feed size is <30mm and the discharge size is about 3mm with uniform particle size and light overcrushing phenomenon. SAG mill: When the weight of the SAG mill is more than 75%, the output is high and the energy consumption …
Capacity. 1-1120t/h. Output size. 10-350mm. Ball mill is a type of grinder machine which uses steel ball as grinding medium, can crush and grind the materials to 35 mesh or finer, adopted in open or close circuit. The feed materials can be dry or wet, they are broken by the force of impact and attrition that created by the different sized balls.
