Cataracting Mill Is Not Power Efficcient

fRod Mills. Fine crusher or coarse grinding machine Capable of reducing 50 mm to 300 m Reduction ratio 15:1 to 20:1. The length of cylindrical shell is between and times its diameter (to prevent the rods become wedged across the diameter). The rod > 6m will bend, so the length of mill is limited at m.

formula for critical speed of a ball mill

The "Critical Speed" for a grinding mill is defined as the rotational speed where centrifugal forces equal gravitational forces at the mill shell's inside surface. This is the rotational speed where balls will not fall away from the mill's shell. Result #1: This mill would need to spin at RPM to be at critical speed. Result #2: This mill's
