Individual ball mills for grinding hard materials

Hundreds of ball mills - made by Hengyang to suit the customers’ particular requirements - operating all over the world. In fact we design, build and install ball mills which are specially adapted to grind hard and even extremely abrasive materials.

Ball Mill Working principle

Fed into the mill through one or both bearing trunnions, the material is ground by impact and friction from the balls. The ground product is discharged from the mill through discharge slots provided in the mill tube, through a discharge wall or through the end trunnion. The design and setting of the discharge slots or discharge wall determine the grain size distribution of the ground product. When performing circuit grinding, the product fineness can be set at the separator. In case of coarse grinding where a downstream screening machine is provided, the product fineness can be preselected by providing a specific mesh width on the screening machine.
