    How to Choose Open-circuit Grinding or Closed-circuit

    The main advantages of closed circuit-grinding is high-efficiency crushing rate, and the production quality is higher. In the same period, closed-circuit has larger production rate. However the disadvantage is that the production flow of closed-circuit is more complex, and costs more than open-circuit grinding.

    Closed Circuit Grinding Of Clinker

    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.
