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 100% critical speed. Result #2: This mill''s

This machine is a 5000lb knee mill and although it''s an open type machine, it is a very good machine. I already have a supplier for precision balls, my cost is around 18 cents per ball in special sizes. At $58 per batch of each size, I don''t want to be playing hit or miss with balls, I''d ideally like to narrow the size down to 3 different options.
