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 describe the residence time distribution.V. Keikkala, H. Lehto (Outotec Oy, Finland), J. Loucas (Outotec, South Africa), A. Paz (Outotec, Australia) and T. Komminaho (Boliden Kevitsa Mining Oy, Finland) Comparing Vertical Roller Mill performance on two different precious metal ores

The vertical roller mill (VRM) is firmly established in cement plants all over the world. The biggest issues facing plants are not due to the equipment itself, but more to do with how well mill maintenance is understood and how the mill is looked after following commissioning.The vertical roller mill (VRM) is popular and widely used for grinding of coal and raw materials. The vertical mill is energy efficient with low specific wear rate. Vertical mill supports drying of the feed material, grinding, separating, and material transport inside the mill. Vertical mill gives optimum grinding performance when grinding ...

These types of mill include vibration mills and vertical roller mills (VRM). While vibration mill have so far only been used for the comminution of coal and industrial minerals, for VRMs the first projects in ore beneficiation have been initiated [7].
