Theory and Practice for

ranges from 35 to 115 percent of Nc. Where particle size reduction is quite critical, a variable speed drive is recommended. This permits the operator to control his mill speed to suit. Most mills rotate at 60 to 65 percent of critical speed (Nc). This formulation is for wet milling where as dry milling needs to be adjusted by 2 to 5 RPM faster.
