The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.
High circulation factors invariably lead to steep particle size distribution curves, if the separation process is has therefore been necessary to adapt special measures to reduce the inclination of the particle size distribution curve, in order to get a cement quality that is similar to the quality of cement ground in a ball mill.
A mechanistic approach based model, matrix population balance model mpbm, is proposed to predict the particle size distribution of the ultrafine grinding products by the stirred ball mill, and.
