• 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.
Grinding is a process in which a coarser feed is ground to a specified fineness of x. However, an over-grinding fineness of y should be specified, and the size interval between x and y (-x+y) is a suitable size fraction for separation. Considering over-grinding in the grinding process, the grinding technical efficiency (E t) (Duan, 2012) is

Loesche developed the 4-roller coal grinding mill with four tried and tested modules for throughputs over 150 t/h. The develop-ment was first realised in 1970 for grinding mills in the cement industry. This number of rollers also enables operation with only one pair of rollers to increase control response availability and flexibility.

Raymond Roller Mills: More than 2,000 roller mills have been supplied since the first mills were designed in the late 1800's. These early machines were the forerunner of the heavy-duty, rugged ring-roll mill manufactured today. The roller mill provides the needed flexibility to economically and efficiently process a wide variety of materials.
The grinding process in ball mills and vertical roller mills differ fundamentally. In a ball mill the comminution takes place by impact and attrition. The comminution in the vertical roller mill takes place by exposing a bed of material to a pressure sufficiently high to cause fracture of the individual particles in the bed, although the ...
