IMPROVED GRINDING CIRCUIT PERFORMANCE

screens in closed circuit grinding, it is interesting to note that research work over many decades has supported the concept of closing grinding circuits with screens. In 1925, E. W. Davis at the University of Minnesota Mines Experiment Station conducted closed circuit grinding tests with a rake classifier, a screw classifier, and a screen.
