اقرأ أكثرBall mills are a fundamental part of the manufacturing industry in the USA as well as around the world. Ball mills crush material into various sizes and extract resources from mined materials. Pebble mills are a type of ball mill and are also used to reduce the size of hard materials, down to 1 micron or less.
اقرأ أكثر- if you will mill a metal, use Argon gas atmosphere or Benzene liquid as an oxidation protection - do not fill your more than by 75 vol% (balls+material) - use balls-to-material ration at least 8:1
اقرأ أكثرThis is because if the solid-to-liquid ratio is too low, the slurry of the ball mill will be too thin which limits the effective use of the energy supplied to operate the mill. Conversely, a higher solid-to-liquid ratio results in a highly viscous slurry that restricts the movement of the balls and reduces the grinding efficiency.

اقرأ أكثرThe 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% ...
