RMs have become the grinding circuit of choice in cement plants for raw meal, clinker and coal grinding due to their lower capital cost and energy consumption compared to ball mills. Loesche GmbH, Germany, has been a leading supplier of roller mills for over 100 years and in more recent times, has expanded by adding a subsidiary
mill is used instead of the former system with two vertical roller mills operating in parallel. Based on these investiga-tions Loesche GmbH has developed a mill for producing raw meal that has an arrangement of six rollers on the grinding table. This mill, designated the LM 60.6 has a grinding table
Loesche developed the 4-roller coal grinding mill with four tried and tested modules for throughputs over 150 t/h. The develop-ment was first realised in 1970 for grinding mills in the cement industry. This number of rollers also enables operation with only one pair of rollers to increase control response availability and flexibility.
The drive of a vertical roller mill essentially the mill gearbox has to fulfill two tasks: The first is to reduce the speed of the electric motor to the selected mill speed and to transmit the torque created by the motor. Secondly, the gearbox has to transmit the grinding forces generated by the grinding rollers, from the mill table
rience with this type of mill when grinding both granulated blastfurnace slag and cement clinker. 2 Structure of the grinding plant Fig. 1 shows the flow sheet for the LM 35.2+2 vertical roller mill in interconnected operation with the rotary kiln. A gas flow of 160000 m3/h is needed for grinding
