The matrix model was used to simulated vertical roller mills in cement clinker and coal grinding lines. The pressure breakage function, B, was determined from the laboratory test data with a hammer device. The results showed that materials are crushed in more than one stage under the vertical roller mill.
There are few studies concerning the process simulation of vertical roller mills (VRMs). In this research work, the application of population balance model for simulation of a VRM in a cement clinker grinding circuit was investigated. The residence time distribution (RTD) was measured, and the...
