TECHNICAL SOLUTIONS FOR GRINDING Norton Abrasives

Abrasive grinding wheels for ball manufacturing are available in both vitrifi ed and organic bond types, in shapes 35 or 35P (plate mounted). The bonded wheel must be very hard and wear resistant due to the slow turning speed of the machine. The balls are placed on a cast iron plate with grooves allowing them to be ground by the bonded wheel. The grinding process is carried out

TECHNICAL NOTES 8 GRINDING R. P. King

The grinding action is induced by relative motion between the particles of media the rods, balls or pebbles. This motion can be characterized as collision with breakage induced primarily by impact or as rolling with breakage induced primarily by crushing and attrition. In autogenous grinding machines fracture of the media

Basic Ball Mill Grinding Circuit

A mill consists of a steel shell supported at each end by a hollow trunnion running in a bearing, lined with steel plates, and driven by belt and gears or by motor and gears. The mill is set at a slight slope and is fed with finely crushed ore and water through one trunnion. When ground fine enough by the load of balls, the pulp is discharged through the other trunnion and run where desired
