How to optimize the grinding process in ball mill for alumina ball 1 in the situation of wet grinding usuallythe total charges of the alumina balls in one ball mill should be not less than 55 of the total ball mill capacity empirical formula of charged alumina ball quantity into ball mill m314xr2xdxlx251000
Apr 11 2017 the grinding balls bulk weight steel density 785 tm3 thus during calculating the grinding balls mass in ball mill after measuring the mill filling degree with grinding media needs to use the grinding balls bulk weight whose diameter was determined earlier
Density 260 gmcc bulk density 160 kgl 350 l 600 kggal 1330 gal this media is a fused magnesium silicate composite made up of 62 sio2 the minimum size is 60 mm available in satellite balls cylinders and spheres this is an excellent alternative to flint pebbles or large glass balls
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
The time that the ore spends in the grinding mill is called retention time this is a very important variable the longer the retention time the more the ore comes in contact with the rods the better and finer the grind becomes to understand this important control it must be remembered that any volume that is added to a circuit must leave the circuit at exactly the same rate all the
Ball mill size as a replacement grinding media wears and reduces in size at a rate dependent on the surface hardness density and composition of the ore ball wear is directly proportional to surface area per unit mass and thus inversely proportional to ball diameter other factors include speed of mill rotation mill diameter mineral density
When choosing grinding media ball two problems are often neglected 1 the harder the grinding media ball well is the better the hardness value is 2 the density of grinding media ball is
Mar 14 2017 grinding media should be evenly distributed in cube surface of them should be smooth in the container the container is weighing when it filled by grinding media as much as possible weighing can be done by any measuring instruments crane scales stationary scales etc it is important that weighing takes by the same measuring instruments and under the same conditions bulk density bulk
Where dbmax is the maximum size of the feed mm is the compression strength mpa e is the modulus of elasticity mpa b is the density of material of balls kgm3 and d is the inner diameter of the mill body m generally a maximum allowed ball size is situated in the range from d 18 to d 24

Grinding media density the range of specific gravity for commercially available grinding media runs from spgr 10 for plastics to spgr 15 for tungsten carbide it makes sense that you wouldnt select a very light grinding bead for a highly viscous system or a very dense grinding bead for a
