particle size down to approximately 1 millimeter mm 0.04 in. in diameter. Fine grinding or milling reduces the particle size down to as low as 1.0 micrometer m 4 x 10-5in. in diameter. Ball mills are the most commonly used piece of equipment for milling. However, vibratory mills, attrition mills, and fluid energy mills also are used.
The ball-milling process uses a higher concentration of grinding media to mill base in which the chambers are designed to maximize the energy transfer. Bead Milling The Dispermat SL model line When a particle size has to be reduced below 10 microns, bead milling is the technique to use.

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 11.5 times the shell diameter Figure 8.11. The feed can be dry, with less than 3 moisture to minimize ball coating, or slurry containing 2040 water by weight.
The power draw is driven mainly by mill diameter and length, ball and slurry charge level, and rotational speed. But the slurry charge in an overflow ball mill doesnt change very much because most of the slurry occupies the void space in between the balls, so as the circulating load increases, the discharge rate also increases.
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 ...
