The geometry of a mill with conical ends is shown in Figure The total volume inside the mill is given by Vm 4 D2 mL 1 2(Lc L) L 1 (Dt/Dm) 3 1 Dt/Dm () The density of the charge must account for all of the material in the mill including the media which may be steel balls in a ball mill.
Ball Mill Operation. Ball mills ride on steel tires or supported on both ends by trunnions. Girth gears bolted to the shell drive the mill through a pinion shaft from a prime mover drive. The prime movers are usually synchronized motors. During rotation, a portion of the charge is lifted along the inside perimeter.
Ball mill that works on the principle of impact is an efficient technique of size reduction through grinding. The size reduction is an important factor for many industrial applications as this process is carried out to increase the surface area, to intimate mixing and to improve dissolution rate, solubility, binding strength and dispersion properties. . Therefore it is important to maintain ...

Aug 11, 2010· Re: MATERIAL RETENTION TIME IN A BALL MILL VRM. You could do that by measuring the material flowrate Q[tons/h] through the mill as well as the quantity M[tons] of material that accumulates within the mill. The retention time, also called residence time, is the ratio (M/Q) [h] .
The performance and efficiency of ball mill generally improves with increasing diameter. All other factors being the same including media size, percent of critical speed, product loading, etc. The rule of thumb for mill scale up is approximately 1(√D/√d) where d is the diameter of the smaller mill and D the diameter of the larger mill.

Ball mill. A typical type of fine grinder is the ball mill. A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.
