All Grinding Mill Ball Mill Manufacturers understand the object of the grinding process is a mechanical reduction in size of crushable material. Grinding can be undertaken in many ways. ... We have has designed a series of single stage speed reducers, which makes it possible to drive the mills by motors with a synchronous speed of RPM.
The standard inching drive motor is a NEMA or IEC frame typically foot mounted to a motor scoop or base plate. Typical motor speeds are either 4 or 6 pole, 1750 rpm or 1170 rpm for 60 Hz applications and 1450 rpm or 970 rpm for 50 Hz applications. The advantage of using a four pole motor allows for a smaller footprint and a smaller brake if
