Via the use of sophisticated instruments and software, we closely monitor the mill impact location to boost the grinding efficiency of your operation. The mills can be operated in open circuit, feeding downstream secondary grinding, or operated in closed circuit as single stage mills generating a finer product size.

Selecting the right grinding mills for your operation requires the serious consideration of a variety of factors, far beyond "what do I want to grind?" and "How fine do I want it?" A starter list of questions would include: Do you need lab grinding mills or production sized mills? Do you need to perform wet or dry milling?

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 ...
