• Characteristics of open

    Abstract 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.
