IMPLEMENTING STRATEGIES TO IMPROVE MILL …
In 1925 E.W. Davis, see Figure 1, conducted tests which compared rake classifiers, spiral classifiers and vibratory screens in the closing of grinding circuits. He concluded that vibratory screens provided higher capacity and better control over grind size than either rake or spiral classifiers. Grinding mills at the time wereWeb
