### Ball Mill Motor Power Draw Sizing and Design Formula

The following equation is used to determine the power that wet grinding overflow ball mills should draw. For mills larger than 3.3 meters (10 feet) diameter inside liners, the top size of the balls used affects the power drawn by the mill. This is called the ball size factor S. ﻿﻿ Rod and Ball Mills by C.A. Rowland and D.M. Kjos @ Allis-Chalmers

### CALCULATION OF THE POWER DRAW OF DRY

For all model based methods, a reliable method to calculate mill power draw for a given mill is required for the calculation of power draw. Morrell (1996) proposed a mathematical model for autogenous, semi-autogenous and ball mills which is based on the motion of grinding charge inside the mill. He also verified his approach with various plant data (Napier-Munn et. al., 1996). In this study ...

### Power draw estimations in experimental tumbling mills ...

01/02/2011  1. Introduction. The power draw of a tumbling mill is known to be an important measure in determining its efficiency. Many models have been derived to predict the power draw as a function of characteristics related to charge motion (Harris and Schnock, 1985, Morell, 1992).While these models have been shown to calculate good approximations of mill power, they have been observed to be
