characteristics of open- and closed-circuit grinding systems
apr 15 2004· the characteristic differences between open- and closed-circuit grinding systems were examined via the use of a continuous vibration ball mill and a blade type classifier. for the same median diameter of the product the rate of powder production in the closed-circuit is about 5% higher than that of the open-circuit.
