Variables in Ball Mill Operation - Paul O. Abbe

In ball milling of dry solids the main independent variables are mill diameter, mill speed, media size, solids loading and residence time. For most companies the production mill already exists so we can ignore mill diameter and focus on the other variables. Mill Speed is one variable that can often be easily changed with a variable frequency ...
