Ball Mill
Basic principle Ball mill is generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system. There is a specific operating speed for most efficient grinding.

As a general rule: 1. For over-flow ball mills the charge should not exceed 45% of the mill volume, 2. For grate discharge mills the charge should occupy about 50% of the mill volume. 3.3 Ball Size at Initial Ball Charge. Ball sizes commercially available for charging in grinding mills range from 10 to 150 mm.

Measuring high voltage or the "static electricity" on your body.
Spark Length. To measure high voltage, attach two large and polished brass balls (2" dia. or larger) to an insulating plate so there is a 1/2 millimeter gap between them. You can verify the 2,800-volt breakdown voltage of this spark gap by using a high-voltage DC power supply to produce sparks between the balls.

Ball Mill Loading
The starting point for ball mill media and solids charging generally starts 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 10%-15% above the ball charge for total of 23%
