Reduction Ratio an overview ScienceDirect Topics

The usual speed reduction ratio of pumping unit gearboxes is about 30 to 1, SAG mills, particularly in American practice, have a large diameter-to-length ratio. Tumbling mills are 35–50% filled with grinding medium, since this gives optimum power draft. The selection of the (average) medium size is a compromise between being large enoughget price
