102315 fPurpose The overall purpose of this lab is to use various pieces of equipment to separate a sample of ore by size. First a sieve is used to separate the different sizes of ore. Next the ball mill is used to grind down the ore. The sieve tower is used again to separate the pieces by size; the pieces can then be compared

Todays ball mills are typically designed to operate with ball charge fillings up to 35% by volume. There are cases where this figure is higher, for example with mill shells designed for higher loadings, but these cases are becoming more rare, with the additional cost of steel becoming prohibitory of this design.

Due to its strong lifting capacity and excellent grinding performance, the trapezoidal liner is widely used in the SAG mill. The structure of the trapezoidal liner is shown in Fig. 1, the main dimensions are: dip angle (tau), length of the top edge (L) and height (h).Dip angle (tau) determines the trajectory of the mediums in the SAG mill, which directly affects the impact speed and ...

planetary ball mill. Planetary mills with a single grinding station require a counterweight for balancing purposes. In the Ball Mill PM 100 this counterweight can be adjusted on an inclined guide rail. In this way the different heights of the centers of gravity of differentlysized grinding jars can be compensated in order to avoid disturbing

The starting point for ball mill media and solids charging generally starts as follows: 50% media charge. Assuming 26% void space between spherical balls (nonspherical, irregularly shaped and mixedsize media will increase or decrease the free space) 50% x 26% = 13% free space. Add to this another 10%15% above the ball charge for total of 23% ...

in variable speed mills, this may be achieved by reducing mill speed; and in both cases this may be achieved by design by increasing the lifter face angle. Traditionally, the number of shell lifters used in a SAG mill is equal to twice the number of the feet in the mill shell diameter (, a 34ftdiameter mill shell would have 68 shell lifters).

Ball mill Most ball mills, even in primary applications, have a finer ore feed size; this requires some impact but not enough to increase the media consumption or even break the liners. Typically, a ball mill lining has a more rounded profile, often like a sine wave, and the size of the waves is selected based on the size of grinding media used.
