When I use ball-end mills, I notice that they prefer to cut with certain parts of the tool. The center is the worst. For the best combination of easy cutting and nice surface finish, ball-ends seem to work best at around 45 degrees off the long axis of the tool.-Mark. 07-15-2013, 03:06 PM #18. Gerry Sweetland.

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 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
