Type of mill: Ball and tube mills. Vertical Roller Mills (VRM). Horizontal roller mill (Roll Press) Roller press with Ball mill.
Survey of compound and closed circuit mills. Virtually all the cement produced in the United States is ground in closed circuit grinding mills; i.e. finished cement grinding mills with a yearly produc tion capacity in 1982 of approximately 104 million short tons – not to take for real cement production are closed circuit separator grinding mills.
For a cement mill: intermediate or outlet diaphragm. For the case of; cement mills with a drying chamber see raw mills. Mill working conditions: ventilation air speed through the mill. Bigger or smaller than 1.2 [m/s]. Material abrasivity. The [%] of slag or pouzzolana content on the fresh mill feed for cement grinding.
