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
How ball mill ore feed size affects tonnage capacity 202066for the purposes of this example we will hypothesize that the the crushing index of the hard ore with the increased energy input of 154 kwt reduces the ball mill feed size to 6500 micrometers as a result the mill output will increase with thi
Feed size ball mill feed size vs ball size 7 replies 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
A total apparent volumetric charge filling including balls and excess slurry on top of the ball charge plus the interstitial voids in between the balls expressed as a percentage of the net internal mill volume inside liners b overflow discharge mills operating at low ball fillings slurry may accumulate on top of the ball charge causing the total charge filling level to be

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls mounted on a metallic frame such that it can be rotated along its longitudinal axis the balls which could be of different diameter occupy 30 50 of the mill volume and its size depends on the feed and mill size
Ball mill feed size mm jun 15 2018nbsp018332then maximum ball size for ball mill grinding is bmm example size of the mill feed 80 passing in microns size 15000 microns 15mm work index for the feed 18 age of mill in critical speed 70 specific gravity of the feed 22 gmcm3 mill

And with the decreased grain size the necessary ball size also decreases olejnik 2010 2011 for each grain size there is an optimal ball size trumic et al 2007 the bigger ball in relation to the optimal one will have an excess energy and consequently the smaller ball mill has less energy necessary for grinding in both
Mortar and grinding ball materials of the grinding tools agate sintered corundum zirconium oxide stainless steel hardened steel hardmetal tungsten carbide grinding ball diameter 50 70 mm max feed size depends on material 5 mm min sample quantity 1 ml max sample quantity 10 ml final fineness depends on material 10 m
More balls with small size results in fine powder 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
Mill grindingwikipedia the power predictions for ball mills typically use the following form of the bond equation where e is the energy kilowatthours per metric or short ton w is the work index measured in a laboratory ball mill kilowatthours per metric or short ton p 80 is the mill circuit product size in micrometers f 80 is the mill circuit feed
First a jar mill grindability test requires a 5 lb 2 kg sample and produces a direct measured specific energy net hphrt to grind from the design feed size to the required product size the second test a bond work index determination results in a specific energy value net hphrt from an empirical formula
