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. Mill Inside Diameter: Feet Metres. Enter the mill diameter inside the shell (excluding liners).
· The separator's efficiency is determined by drawing a Tromp curve based on particle size distribution analysis. The separator's performance can be improved by changing the adjustments or replacing worn components. The operational controls are also reviewed for optimized mill operation.
