The CKP mill was used for the precrushing of cement clinker in a Chinese cement plant. The mill has similar grinding rollers and grinding table to the typical rollerrace mill, but has no airclassifier inside the mill body. However, part of the ground product was returned to the mill to enable smooth operation.
