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 the large balls tend to break down the coarse feed materials and the smaller balls help to form fine product by reducing void spaces between the balls pharmaceutical uses of ball mill 1 the small and
Where r radius of ball mill r radius of ball for r 1000 mm and r 50 mm n c 307 rpm but the mill is operated at a speed of 15 rpm therefore the mill
Jun 26 2017 given the new effective cutting diameter a compensated speed will need to be calculated if you are using less than the cutter diameter then its likely your rpms will need to be adjusted upward see figure 3 key adoc axial depth of cut d cutting diameter d eff effective cutting diameter r tool radius dia2 rdoc radial depth of cut
This formula calculates the critical speed of any ball mill most ball mills operate most efficiently between 65 and 75 of their critical speed photo of a 10 ft diameter by 32 ft long ball mill in a cement plant photo of a series of ball mills in a copper plant grinding the ore for flotation image of cut away ball mill showing material flow through typical ball mill
The minimal magnitude of ball size is calculated in millimeters from the equation where dbmax is the maximum size of feed mm is compression strength mpa e is modulus of elasticity mpa b is density of material of balls kgm 3 d is inner diameter of the mill body m
In grinding selecting calculate the correct or optimum ball size that allows for the best and optimumideal 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 andor mill liner wear and
Where dbmax is the maximum size of feed mm is compression strength mpa e is modulus of elasticity mpa b is density of material of balls kgm 3 d is inner diameter of the mill body m generally a maximum allowed ball size is situated in the range from d 18 to d 24
The ball mill consists of the mill base and the mill jar theres one more important component to a ball mill though the media the balls of heavy material which fall upon and crush the chemicals are called the milling media
