involve grinding). With Lloyd's ball milling book having sold over 2000 copies, there are probably over 1000 home built ball mills operating in just America alone. This article borrows from Lloyd's research, which was obtained from the commercial ball milling industry, and explains some of the key design criteria for making your own ball mill.

The starting point for ball mill media and liquid charging is generally as follows: 50% media charge. Assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space) 50% x 26% = 13% free space. Add to this another 45% to 50% above the ball charge for total of 58% ...

to ball filling variation in the mill. The results obtained from this work show, the ball filling percentage variation is between 1.2– 3.7% which is lower than mill ball filling percentage, according to the designed conditions (15%). In addition, acquired load samplings result for mill ball filling was 1.3%.

Ball filling and mill fractional speed were kept constant respectively at 20% and 60% while slurry filling was varied from 0% to 300%. Using a high speed video camera, the motion of the charge was captured. ... The mill was then stopped and the solution was added to make up the next level of slurry filling. The mill was started again and filmed ...

The Ball MillScan utilises the latest in digital signal processing techniques available to provide an accurate of the change in the mill fill level (vectors). The system is made up of 1 wireless shell sensor and 2 wired inlet/outlet sensors. The signals may be used in an automated control loop or for improving manual control.

We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill.

The measurement of the ball charge volume load (or filling degree) is essential to maintain the absorbed power of the mill and consequently the mill production. The most common way to evaluate the filling degree is the measurement of the free height inside the mill (vertical distance between the top of the charge and the lining in the mill axis).

I've worked around but have not had any hands on experience with ball mills used to crush rock down to about 100 mesh during ore extraction in copper / gold mines for many years. There's also what are called rod mills that use long lengths of steel rods to crush the ore while the mill is rotating.

The filling level of 30 % often turns out to be the most economical nominal value. However, filling degrees around 24 – 26 % are energetically the better option for most plants, although the production is lower. Hence, the ideal filling degree always depends on the operator's target.
