Application of perfect mixing model for simulation of
application of vertical roller mills (VRMs) for ore grinding is a part of the second strategy [1]. In the mid 90's, LOESCHE introduced its VRMs with the 2+2-technology for grinding clinker and slag [2]. The grinding parts of a Loesche mill are illustrated in Figure 1 [1]. Several characteristics of VRMs are advantageous for the challenges inThe vertical roller mill is an important crushing and grading screening device widely used in many industries. Its classification efficiency and the pressure difference determine the entire producing capacity and power consumption, respectively, which makes them the two key indicators describing the mill performance.

Selected Aspects of Modelling and Design Calculations of Roller Mills
An analysis of construction was conducted in this study, and the guidelines for designing roller mills used commonly in the agri-food, chemical, power and construction industries were presented. Quick designing of the machines required existence of adequate mathematical models. Within the framework of the study’s realization, a mathematical In this study, all the samples were obtained from the clinker grinding line 2 of the Ilam cement plant in the Iranian province of Ilam-karezan. Used a VRM (Loesche mill) with 160 t/h to grind the clinker, fed into the mill during the grinding process (%90 passing 32 mm).
