Exploring ball size distribution in coal grinding mills

2014-5-1  To apply to industrial mills two main considerations need to be taken into account; matching the selection function to the prevailing ball size distribution in the mill and up-scaling the parameters to cater for the effect of increased mill diameter. 3.2.1. Adjusting the selection function to match ball size distribution

Ball size distribution for the maximum production of a

2015-11-1  The simulated product size distributions were found to display a close match with the measured product from an operational mill. Based on the maximum production of floatable particles, the best combination of make-up ball size was determined in relation to feed flow rate, feed size distribution and ball

Calculate and Select Ball Mill Ball Size for Optimum

2021-1-22  In 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 Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize “just in case”. Well, this safety factor can cost you much in recovery and/or mill liner wear and

THE OPTIMAL BALL DIAMETER IN A MILL

2012-5-15  which can grind efficiently in a mill, c is the exponent which characterizes the ball size distribution. The condition for efficient grinding, defined by Eq. 7, will be fulfilled when the grain size distribution and the ball size distribution are the same, which means that the parameters of both distributions are equal in Eqs. 7 and 9: m c. (10)

Effect of ball and feed particle size distribution on the

2018-6-1  In this article the effect of grinding media size distribution and feed material particle size distribution (PSD) on the product fineness requirements were investigated. A model free approach called the Attainable Region method was then applied in order to optimize the product size fineness in terms of the feed size and ball mix.

Influence of ball size distribution on grinding effect in

Abstract The law of ball size distribution in the horizontal planetary ball mill is studied by the discrete element method. The results show that the maximum impact energy could be acquired when filling rate is 24%, moreover the biggest mean contact force and the highest energy utilization ratio of balls could be acquired when the speed ratio is 1.5.

The effect of ball size distribution on power draw, charge

2018-3-19  40%. The effect of ball size distribution increased with increasing mill filling and for the mill filling of 35%, the ball size distribution had the maximum effect on the power draw. When the mill charge contained mono-sized balls, the ball flow regime inside the mill transited to the cataracting and impact breakage was the main breakage mechanism.

Comparison of alumina ball size distribution in two

The mills were unloaded and the ball charge was screened in order to establish the ball size distribution. For both mills, the balls retained during the unloading were compared to the balls retained at the beginning of the process, and additionally, they were compared to the results obtained by the Swebrec adjusted distribution model.
