### How to Choose Open-circuit Grinding or Closed-circuit

· 01 The specifics of two grinding ways. Opening-circuit grinding is that in the grinding operation the material is fed into the mill and discharged after a grinding directly into the next mill or the next process.. The advantages of opening-circuit grinding are simple processing flow and lower investment cost. While the disadvantages are lower production rate and large energy consumption.
