Wet Grinding Mills Custom Milling Consulting, Inc.

May 02, 2014  Wet grinding mills also referred to as media mills are used to reduce particles in liquids. The mills make it possible to break down, what are known as agglomerates into their finer individual particles. This increases color development, gloss transparency, particle size distribution and can even increase chemical activity.

Problems in population balance modeling of wet grinding ...

Sep 01, 1992  The Population Balance Model, PBM, contains flaws making its use for effective simulation and control of milling circuits questionable. Presented is an analysis, based on published experimental wet grinding data, showing that the assumption of linearity, used in solving the PBM, is certainly wrong in many grinding mills and wrong for most commercial wet grinding circuits.
