For the ball mill of the same specification, the closedcircuit process is 15~20% higher than the open circuit process; in the closed circuit operation, selecting the proper powder selection efficiency and cycle load rate is an important factor to increase the mill output. 7, Powder selection efficiency
Grinding systems are either ''open circuit'' or ''closed circuit.'' In an open circuit system, the feed rate of incoming clinker is adjusted to achieve the desired fineness of the product. In a closed circuit system, coarse particles are separated from the finer product and returned for further grinding.
