A study of the exit classification effect in wet ball milling
Method 1 uses a hypothetical exit size classifier, Method 2 considers different axial flow velocities for different sizes, Method 3 uses modified specific rates of breakage and Method 4 allows for non-first order grinding kinetics. The methods were tested on literature data from mills of 0.56, 0.82 and 3.35 m in diameter, wet grinding the same ...
