What's the Difference Between SAG Mill and Ball Mill ...

The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...

Bull Nose End Mills (Corner Radius) Carbide

Bull end mills are simply corner radius end mill cutters. These radius end mills are single ended tools used for making corner radii at the bottom of a milled shoulder. Corner radius end mill cutters have a stronger milling edge than square end mills, so feed rates may be increased and yield longer tool life and greater productivity.
