Figure-1. Vertical roller mill for cement grinding [13]. VRM shown in Figure-1 uses hydraulically hard-pressed conical shape 2-4 rollers against the horizontal revolving grinding table. To enhance comminution, the axes of table and rollers do not traverse in the plane of the table and approximately 150 inclination angles between
The quadropol® concept for coal or pet coke grinding, with adapted table speed and high efficiency separator sepol®, ensures a safety mill operation and serves reliable the kiln burning process. Mombasa Cement Ltd. ordered a QMK² 24/12 with three roller units for the 5,000 tons per day kiln line.
Abstract. Vertical roller mills (VRM) have found applications mostly in cement grinding operations where they were used in raw meal and finish grinding stages and in power plants for coal grinding. The mill combines crushing, grinding, classification and if necessary drying operations in one unit and enables to decrease number of equipment …

A mathematical model of vertical rolling process with the consideration of mechanism displacement is proposed. Using Γ function and parabola function to describe edge deformation, the corresponding 3D velocity field, strain rate field and total power functional are derived. Simultaneously, an analysis method of mechanism deformation is …
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 tank-in-series and Weller models were employed to ...
