The schematic layout of a cement milling circuit is shown in Fig. 1. The mill is fed with raw material feed. After grinding, the material is introduced in a high-efciency classier and separated into two classes. The tailings refused part are fed back into the mill while the nished product accepted part exits the milling circuit.
