learn moreHow proper shaft sizes are determined MRO
The calculations for shaft diameter are not quite as straightforward for a vertical hollowshaft motor. Two variables — the outside and inside diameters of the hollowshaft — are not standardized, making it impossible to simplify the calculation with a ratio. For this reason, it is easier to demonstrate if a specific hollowshaft is sufficient for a given power rating. Example 3: A 200hp

One crankshaft manufacturer tested some shafts that were ground down to .010˝, .020˝, .030" or even .040" undersize and found that there was less than a 4% reduction in the fatigue life of the undersize shafts. Most crankshafts are engineered to be about four times stronger than required, based on mathematical stress and load calculations, so a 4% reduction in fatigue life is virtually

Attrition between grinding balls and ore particles causes grinding of finer particles. SAG mills are characterized by their large diameter and short length as compared to ball mills. The inside of the mill is lined with lifting plates to lift the material inside the mill, where it then falls off the plates onto the rest of the ore charge. SAG mills are primarily used at gold, copper and
