Abstract It has been 10 years since the JK size-dependent breakage model was developed (Shi and Kojovic, 2007). This series of papers present 20 applications of the model for the mineral and coal industries. Part 3 of this series reviews its application to modelling comminution equipment. It is demonstrated that the JK size-dependent breakage model not only can be used for modelling particle breakage, but also can be employed as a basic structure for modelling comminution equipment. This is different to the traditional equipment modelling approaches, in which the population balance models are dominant. In this energy-size reduction modelling approach, the JK size-dependent breakage model provides a key mathematical template to rationally link the size reduction as the equipment model output with ore breakage property and specific energy as the two model inputs. Five case studies are reviewed, which includes modelling of a hammer mill for coke feed preparation, a vertical spindle mill for coal pulverised fuel grinding, a ball mill for batch grinding and continuous operation, HPGR simulations based on piston press testing data, and high voltage pulse disintegration of ores. A common feature of these models is that they all incorporate the measured material breakage characteristic parameters and machine operational conditions that are represented by the size-specific energy relation. The energy-size reduction modelling approach permits the simulations of the effects of changes in ore/coal and machine operating conditions on comminution product size distribution.
