For primary grinding, the ratio could vary between 1:1and 1.8:1. For fine regrinding in open circuit, the ratio ranges from 1.3:1 to 1.5:1. Some ball mills are separated in to compartments by grates. The grates hold back particles above a certain size for additional grinding. The compartments could contain different ball sizes.
MATHEMATICS OF GRINDING Critical Speed:-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. Mills are driven, in practice, at speeds of 50-90% of critical speed, the choice …
