Jan 14, 2004 The maximum fineness attainable by open circuit stirred mill tests is 6200 cm 2 g. ampx02022 During the open circuit tests, specific energies excessively increases beyond Blaine values of 4500 cm 2 g which corresponds to a specific energy consumption of 60 kW ht. Beyond this point, further grinding can be obtained for the speeds above 600 rpm.
brief description of a cement mill Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls crushes the clinker.
Open circuit grinding consists of one or more grinding mills, either parallel or in series that discharges a final ground product without classification equipment and no return of coarse discharge back to the mill.
