A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.

effect of ball size distribution on the selection function whereas the original equipment manufacturer recommended ball mixture was used to validate the model. Results show that with the six parameters abovementioned estimated, the charge
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.
Ball Mill Introduction, Ball Mill Working Principle, Ball … Ball Mill is a key equipment which repulverises the material after it is crushed. … Weight of ball (t) Size of feed opening (mm) size of outputting feed (mm) Production (t/h)
Then the multiple would be closer to 13 times the maximum particle size fed to the ball mill. Get Price The effect of ball size on mill performance ScienceDirect. This equation produces a maximum in S, and the particle size of the maximum is related to ball diameter by x m = k 1 d 2. The variation of a with ball diameter was found to be of the form a = k 2 / d 1.5 . Get Price Ball Mill ...

Centrifugal Ball Mill S 100 achieve a very high final fineness down to the submicron range. The feed size depends on the mill and can have a maximum size of. 10 mm.
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.
The maximum power draw in ball mill is when ball bed is 35 40 % by volume in whole empty mill volume. Considering that ball bed has a porosity of 40 %, the actual ball volume is considered to be 21 24 % of the empty mill.
