Jan 15, 202001 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.
