The Effect Of Ball Size Diameter On Milling Performance

had decreased for the -2 mm 1.4 mm mono-size feed compared to the bigger -4 mm 2.8 mm mono-size feed. This therefore shows that should the material feed size continue to decrease, the smaller balls will perform better than the larger balls during milling, as was mentioned by Katubilwa et al. Effect of ball diameter size on mill power draw

Effect Of Ball And Feed Particle Size Distribution On The

Jun 01, 2018 Fig. 5 shows the variation of size class 1 M1 with the milling time for the two feed size distributions. For this coarser feed the 50 2010 mm ball diameter mix breaks the material at a faster rate compared to the other ball matches. The availability of a ball size for a particular feed size ensures breakage occurs at a faster rate.

How Coarse Can Ball Mill Feed Be Grinding

Feeding 15mm to a ball mill this size is not typical - much larger ball mills 21 or 7.0m diameter typically get 12-16mm feed from what I have seen in my experience With regards to 3.5 - 4 media, typically for Ball mills of this size 16, max size of ball used should be around the 50-60mm.

Feed Size Vs Ball Size Grinding Amp Classification

One can argue the f50 is a more realistic value since balls wear and the average ball size might be closer to half the maximum. Then the multiple would be closer to 13 times the maximum particle size fed to the ball mill. A f80 6 mm would need a ball size of 75 mm.

How To Size A Ball Mill Design Calculator Amp Formula

May 15, 2015 1 Rod milling a rod mill with a diameter of 2.44 meters, inside new liners, grinding wet in open circuit. 2 Ball milling a ball mill with a diameter of 2.44 meters, inside new liners, grinding wet in

Optimum Choice Of The Makeup Ball Sizes For Maximum

Sep 01, 2013 It was found that the optimum composition depends on various factors, including the feed size, the product size, the mill diameter and the breakage parameters. In all cases, binary mixtures of two ball sizes 50.8 mm and 25.4 mm performed better than a mixture of the three ball sizes.

Effect Of Ball And Feed Particle Size Distribution On The

Jun 01, 2018 The graphs show that for a courser feed a three ball mixture 50 20 10 mm will provide the much required largest amount of size class of interest. For a finer feed a binary mixture i.e. 20 mm 10 mm will satisfy the objective function which is to get more of the -150 75 m size class material. Download Download high-res image 359KB

How Coarse Can Ball Mill Feed Be Grinding

With regards to 3.5 - 4 media, typically for Ball mills of this size 16, max size of ball used should be around the 50-60mm. I feel that a 4 ball in a 16 Ball Mill is too large and more suited to SAG Milling. You risk damaging liners rubber, composite or full steel as well as trommels and feed chutes in the process.

How Can One Select Ball Size In Ball Milling And How Much

Jan 31, 2015 As a thumb rule powder to be milled should be taken as 25 of total ball weight. If the quantity of charge is very less then milling balls will start to collide with each other and no milling will...
