Everything you need to know about clinker/cement Grinding
The quantity of grinding aid used in a particular mill is dependent on the size of the mill, feed size, product size, type of clinker being ground, etc For instance, in large diameter ball mills, the impact force of the grinding media is so great, that a high material surface unbalance prevails in the mill when grinding all types of clinker, thus requiring aConventional clinkergrinding ball mills with a diaphragm (Source: Jankovic et al, 1995) The coarse clinker is ground in the first compartment where larger balls (80, 60, 50 mm) are present and the fine grinding is achieved in the second compartment where smaller balls (below 25 mm) are usedConventional Clinker Grinding A New Approach To The
