• Vertical roller mill (VRM) • Ring roller mill or Horo mill Even though there are various types of systems available for cement grinding, ball mills are predominantly used machines for cement grinding in large number of cement plants. In this paper authors are covering the process diagnostic study of Ball mill for cement grinding. 2.
2) The pre-grinding adds a roller press to the cement grinding system. In this system, the clinker is extruded circularly, dispersed and separated, and becomes powder with diameter less than 2 mm; Gradation of Grinding Media. The gradation of grinding media is also an important factor in improving the efficiency of ball mills.
