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.Optimizing your SAG mill operation - International Mining,The mill discharge from these mills consists of slurry, which goes to the ball mills for further grinding, and coarse pebbles/rocks, which are crushed and sent back to the mill. To maximize the capacity of these circuits, the general practice is to use grates with pebble ports (reaching 100 mm) instead of normal grate openings to increase the pebble removal.Super Orion Ball Mill S.O. | HOSOKAWAMICRON CORPORATION,The complete ball mill is bedded on a steel or concrete frame designed to rest on a defined number of load cells.
