Abstract A specific energy-based size reduction model for batch grinding ball mills was reported in a previous paper (Shi and Xie, 2015). A discharge function modified from the Whiten classification efficiency equation has been incorporated in the size reduction model to extend its applications from batch grinding to continuous operation. Five sets of the industrial ball milling survey data ...
ondary ball milling. In these circuits the SAG mill is the largest energy consumer. In many engineering projects either a power equation and/or a speciﬁc energy equation are used for the designing of these mills but not always with acceptable results. In general

A particle size reduction model has been developed as the first component of an upgraded ball mill model. The model is based on a specific energy-size reduction function, which calculates the particle breakage index, t 10, according to the size-specific energy, and then calculates the full product size distribution using the t 10-t n relationships and the mass-size balance approach.
