Classifier performance during dynamic fine grinding in ...

Fine grinding in fluidized bed opposed jet mills leads to product accumulation. • The determined high solid load at the classifier leads to a fish-hook effect. • Accumulation of fines is enhanced by high classifier speeds and holdups. • The time for the product to reach a steady-state increases with higher holdups. •
