Grinding Operation an overview ScienceDirect Topics

A mill ready to start a grinding operation could be around 150 t in dead weight. Thus, the initial torque on the mill shaft is very high and an electric drive motor and drive is designed to cope with it. Figure 8.11 illustrates a typical change in torque with increasing speed of motor. It can be seen that the peak torque of 140% of the running torque at start-up is typical.

TOWER FINE MILLING EXPERIENCE AT MOUNT ISA MINES

The Mount Isa Lead-Zinc Concentrator Tower mill is used for fine grinding of fine grain particles near the tail of the circuit. It had a similar performance in both the LGM circuit (Table 3) and the current zinc retreatment circuit (Table 4). The circuit operating (mill+cyclones) index was low in both applications suggesting efficient size reduction.
