The rod mill motor power is in horsepower at the mill pinion-shaft. For different length rod mills power varies directly as rod length. For difference between new and worn liners increase power draw by 6%, and adjust for bulk density per Table A. Wet grinding rod mills are normally used in minerals processing plants.
The design results show that the minimum shaft power required to drive the ball mill is 0.2025 horsepower, the length of the mill at a fixed mill diameter of 210 mm is 373 mm, and the required shaft length and diameter are 712.2 mm and 30 mm respectively.
The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum 'chunk size', product size as P80 …

A composite shaft is a shaft made up of two different diameters. The composite shaft may experience twist when they subjected to the torque. This twist can be obtained in these composite shaft, be based on the torque applied position when the shafts in series and parallel.
The properties of steels made by rolling of billets are mainly dependent on the process of forming. The performance of the rolling mill depends on the Universal joint shaft through which the power is transmitted to the rollers of a mill. This report mainly focuses on the analysis of universal joint shaft for rolling mills because this shaft is subjected …
