Bhasker has investigated flow paths in the classifier of a roller mill, and trajectories of 25 μm coal particles were obtained by applying computational fluid dynamics (CFD) [12]. And for a simplified industrial pulverizer, Vuthaluru et al. have conducted numerical simulation to compare the motion of air and 100 μm and 500 μm coal particles

The fundamental difference between the ATLAS and other tableroller mills is the bearing arrangement for the grinding table which is incorporated into the base of the mill. This enables an operation with a standard design gearbox instead of the typical gearboxes with integrated bearing section with long delivery times.

the mill table, due to mill and roller's relative movement, materials get into the grinding layer between the roller and the mill. In suspension between classifier and table, material drying transpires will takes place. The unstable grinding bed causes the VRM to vibrate. Water is directly sprayed into the bed to make dry mill feed, which is

The application of vertical roller mills (VRMs) for ore grinding is a part of the strategies against rising energy consumption (Reichert et al., 2015). The VRM technology was introduced in the mid'90s for grinding clinker and slag by LOESCHE (Schaefer, 2001). Fig. 1 illustrates the grinding parts of a Loesche vertical roller mill.
