Calculate and Select Ball Mill Ball Size for Optimum Grinding. 201981&ensp·&enspIn Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a …

• ### ball mill design/power calculation

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 and maximum and finally the type of circuit open/closed

• ### 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 energy required for grinding in a ball mill

The grinding-product size, P, in a Bond ball mill, which is given by the aperture size which passes 80% of the grinding product as a function of the aperture size of the test screen Pk, can be expressed by the formula P= P k K 2. These functions for G and P enable us to calculate the value of Wi for any other size of grinding product if we know the work index Wi and aperture size of the screen Pk
