    Mill Speed an overview ScienceDirect Topics

    Mills operating below 75 rpm are known as low-speed mills. Low-speed units include ball or tube or drum mills,which normally rotate at about 15–25 rpm. Other types of mills, e.g., ball-and-race and roll-and-race mills, that generally fall into the medium-speed category may also be included in this category provided their speed is less than 75 rpm.

    Advantages of low speed drive solutions PACE

    Low speed synchronous motors with frequency converter control can generate sufficient torque to start a mill turning without needing an air clutch. This is a major advantage of variable over fixed speed drives, because eliminating the clutch from the system reduces maintenance needs.

    LSSM = Low Speed Synchronous Motor Drive Operation

    In the world of mining and milling the “electrical term” LSSM stands for “Low Speed Synchronous Motor” and usually means a mill where the motor rated speed is in the range of 10 RPM, the same speed as the mill turns. A high speed motor can run at 900 RPM and uses a gearbox to turn down the speed. A medium speed motor runs in the range of 100 RPM and uses the

    What's the minimum frequency (speed) can a VFD run?

    It is actually a low frequency of a fraction of a Hertz, to several Hz depending on the size of the motor (VFD) and its rated slip. The choice of frequency is a compromise between effective induction on the rotor, and minimum magnetizing current (higher frequency) and operation in the right part of the (reduced starting frequency) torque-speed curve (lower frequency is preferred).
