Remarks: Basic standard of mill selection:
(1) Medium grindability of raw material (MF) is 0.9~1.0.
(2) The Maximum moisture content of raw material is 7%.
(3) The granularity of fine material is 80μmR 12~15 %.
(4) The moisture content of fine material is 0.5~1.0 %.
(5) The above conditions are similarly suitable for limestone grinding. The specific model selection depends on the characteristics of materials.
