Dry grind mills can be used in conjunction with air classifiers or screeners to form a closed grinding process loop (Figure 5). By continuously classifying out fines and return-ing oversize material to the mill, such systems can very efficiently provide sharp particle-size-distribution grinds. As a rule of thumb, dry grinding generally will achieve
