mill drive is in inching mode, one rotation of the mill is all you need. The mill will reach the exact angle that was preset by the operator, and the procedure does not need to be repeated. At the end of the inching operation, the SIMINE Gearless mill drive stops the mill with balanced charge, and with no time-wasting oscillations.In creep-
Major Grinding Mill Manufacturer Eaton's new hydraulic inching drive rotates grinding mills slowly for startup and maintenance work Market Served: Mining Location: United States Segment: Mineral processing Challenge: Supplying a new and improved inching drive for grinding mills that would be easy to disengage and offer variable speed control.
advantage over an inching drive, because the inching torque is transmitted by the dual drive system to the mill through both motors and both pinions simultaneously. When an inching drive is used, all of the inching torque is transmitted through only one of the two pinions, requiring a larger diameter pinion shaft and in turn larger pinion bearings.
