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...
Dry batch milling tests were performed in a laboratory scale ball mill measuring 302 by 282 cm The mill specifications are given in Table 1 A constant ball load of 20 was maintained in all the tests with a ratio of 05 for binary and 033 for trinary ball mix Table 1 Specifications of the mill...

All Answers 4 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 start to collide with each other and no milling will take place Ball size depends on initial size of charge and ranges from 10mm-150mm dia...

All Answers 15 For milling of coarse material you need big milling balls for milling of fine powders you need fine milling balls Size of the milling balls should not be more than 3-4 orders of magnitude larger than your final grain size you want to achieve Once you reach this grain size and you want finer powder you have to shift to smaller milling balls...
In ball milling, the desired particle size is achieved by controlling the time, applied energy, and the size and density of the grinding media The optimal milling occurs at a critical speed Ball mills can operate in either a wet or dry state...
