Effect of ball size on the performance of grinding and

2013-7-18 · The makeup balls are 80 mm forged alloy steel balls and the average ball consumption is 750 g t1 ore ground. In order to optimise ball size distribution inside the mill, based on the previous investigation, instead of using only 80 mm makeup balls, a combination of 80 and 60 mm (75 and 25 wt-%) ball charge was used in one of the grinding lines.

2016-10-21 · ABSTRACTZinc oxide (ZnO) was wet milled using inert Al2O3-ceramic balls having different diameter at different milling intervals and the milling efficiency of the resultant dispersion was followed through particle size analysis and zeta potential measurements. The results indicated that small-sized balls improved the milling efficiency. The highest share (%) of lower-size particles was ...

Calculate and Select Ball Mill Ball Size for Optimum

2019-10-14 · 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 tear.

Effect of ball and feed particle size distribution on the

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.

The Effect of Ball Size Diameter on Milling Performance

Ball Size as Initial Charge. Commercial ball sizes 10 150 mm; Number, size and mass of each ball size depends on mill load and whether or not the media is being added as the initial charge. For the initial chargin of a mill, Coghill and DeVaney (1937) defined the ball size as a function of the top size of the feed, i.e., dV = 0.40 KF...
