Analysis and Optimization of Grinding

This work concentrates on the energy consumption and grinding energy efficiency of a laboratory vertical roller mill (VRM) under various operating parameters. For design of experiments (DOE), the VERTIMILL® is TON’s gravity-induced, vertical stirred mill. Its vertical configuration allows for large throughputs while maintaining a small footprint in your circuit. The VERTIMILL® can bring up to 40% savings in energy consumption in some cases, and helps in reaching excellent recovery rates by producing a sharper particle distribution.TON Vertimills

The basic structure of the roller mill includes the grinding roller, the grinding body, the force generation and transmission mechanism, airﬂow, and the device for easy replacement. It can be divided into vertical roller mill, horizontal cylin-derrollermill,highpressurerollermill,Raymond mill, and column mill. Vertical Roller MillThe application of vertical-roller-mills (VRM’s) for ore grinding is part of the second strategy. The grinding parts of a Loesche mill ( Fig. 1) are a rotating table (1) with a horizontal grinding track and rollers (2), which are pressed onto the table by lever arms and a hydro pneumatic spring system.Research of iron ore grinding in a vertical-roller-mill
