factor in the grinding mill selection, other factors, such as reliabil ity of mill drives and power source, are important elements in the decision making process. This article examines how the NPC calculation, plus reliabil ity and power source, influence SAG mill selection. SAG mill drives There are two types of SAG mill drives.
A horse mill is a mill, sometimes used in conjunction with a watermill or windmill, that uses a horse engine as the power source. Any milling process can be powered in this way, but the most frequent use of animal power in horse mills was for grinding grain and pumping water. Other animal engines for powering mills are powered by dogs, donkeys ...

To test the Quadrex Mill Drive torque dividing system under the most severe operating conditions, a fullscale instrumented test bench was designed and built. The test bench, driven by a variable speed motor, is composed of two torque ...
For fully autogenous grinding the mill drives are usually selected with a rating so that the drive is slightly oversized, to allow for variations in ore specific gravity and charge level. For example, if the ore is quite uniform and normal operation is expected to be 30% charge, a drive is selected at, perhaps, a 35% charge.
