55 known as the distribution function [45, 46]) describes the distribution of fragment sizes obtained after a breakage of particles of size xj.Thus, b1j, b2j, …, bnj are the mass fractions of particles in size classes 1, 2, …, n after a breakage of particles in size class j. The mechanism of breakage is illustrated in  by a diagram shown in Fig. 3.

The MPE "K" roll designs utilize a unique cracking process, wherein each mating peak and valley acts as a fulcrum point that actually "cracks" each particle There are over 30 different roll corrugations for "F" and "K" rolls, with each being optimal for a specific particle size reduction applications.
When the size distribution curves of the feed and product are parallel, the reduction ratio remains constant for all particle sizes, and the Work Index calculated from the 80% passing size is equivalent to that calculated on the basis of any other selected percent passing size.

Gentle grinding action and quick discharge of properly sized particles ensures tight particle size distributions (PSDs) when comminution is your goal. In wet size conditioning applications, drying time is greatly reduced, due to the increased surface area of the wet product produced by Comil®.
The kinetic models of the grinding process are based on mass-balance equations describing the process in the different size intervals.In general, a solution of (5) describes the change in particle size distribution of the ground material as a function of the grinding time.
can shift the trade-off between the desired particle size distribution and throughput and change the operational constraints for the grinding mill. To be successfully accepted, multivariable controllers in mineral processing must provide easy or automatic
All of these variables affect particle size, shape, and grinding efficiency. This type of grinding is very good for abrasive materials to prevent contamination. The grinding media as well as the interior surfaces of the mill can be lined with abrasion resistant materials suited to the material being ground.
Since the time of grinding is comparatively short, it is assumed that the effective particle diameter is the average of the mean particle size of the feed and of the product; the mean particle size of the feed and product being assumed to be the sieve size which passes (or retains) 50 % of the sample.
