Pre-grinding to a fineness of 2500- 3000 Blaine is per formed in the coarse grinding mill. In the open circuit fine grinding mill, fine particles of up to 6000 Blaine can be attained [143b]. The one-compartment fine grinding mill is filled with 4- 8 mm cylpebs grinding media; because of its small size, the grinding media are called minipebs.
