Vertical roller mills (VRMs) are wellestablished grinding equipment for various tasks in the coal and cement industry. There are few studies on simulation of VRMs. In this research work, appliion of perfect mixing model for simulation of a VRM in a cement grinding plant was investigated. Two sampling surveys were carried out on the VRM circuit.
· Comparison of vertical roller mills with tumbling mills on the lab and pilot scale • Lab scale tumbling mills arranged in the (energy) optimized comminution sequence • Energy control by torque measurement, dispersity control by permeametry • Based on energy expense for grinding only the tested vertical mills are more efficient.
· Vertical roller mill Feed size: f (Roller Ø ) Material bed Feed material Max Particle size in feed: 58 % of roller diameter Grinding force = Roller weight + (pressure) Force Table moves with drive Roller rolls freely with table 8/7/2013 5.
As a basic principle, all QMR² roller mills are equipped with the thyssenkrupp Industrial Solutions Machine Protection System. It monitors the gear unit and other important mill components to shut them off in case of overload. The monitored parameters include, for example, roller speed, roller vibration and hydraulic pressure.

This is of the updrive type consisting of a roll stand, mill spindles, a vertical gear reducer with pinion stand and a motor. The gear reducer and motor are installed on a concrete frame so that they are protected from roll cooling water and mill scale. Lifting device is installed under the roll stand to adjust the caliber position to pass level.
Vertical roller mill is a kind of grinding machine for cement, raw material, cement clinker, slag and coal slag. It has the features of simple structure and low cost of manufacture and use. Vertical roller mill has many different forms, but it works basically the same. All of these forms of machine come with a roller (or the equivalent of ...
