An energy-mass-size balance model has been successfully applied to simulate the dynamic response of an open circuit grinding mill. Simulation results have been obtained showing the dynamic response of the mill to changes in mill operating parameters. Simulations were implemented in a MATLAB programming environment.

Recently, the vertical roller mill having great grinding performance is widely applied to the raw material grinding process. However, tube mill, which has about 30% poor grinding performance as power consumption, has been still used many existing cement plant. The improvement of this tube mill grinding system is highly expected. Descriptions
Mass Balance Problem. The mass balance problem arises from possible loss of products caused by adsorption of material on the shock tube walls or on the injection system on the way to the gas chromatograph. ... Mass size fractions are not conserved through grinding devices (SAG mill and ball mills). Therefore there is no mass conservation ...
Therefore, grinding is generally analysed using the energy-size relationship models such as the Bond, the Kick, etc. However, problems arise in the scale-up procedure due to the lack of information about grinding kinetics and mass transport in these models. Therefore, grinding can also be analysed using the kinetic (population-balance) models.
