diameter in ball mill
Ball Mills : United Nuclear, Scientific Equipment & Supplies, …
The larger diameter the ball mill, the larger particle size it will handle and the more aggressive the milling will be. The rule of thumb is if you can grind the material into a powder using a mortar & pestle, a Ball Mill will most likely work for the purpose. Ball Mills work by employing various types of media (either steel, ceramic or lead ...

Ball milling: a green technology for the preparation and
The ball mill worked by cracking the cellulose microfibrils along their longitudinal axis leading to nanofibers with a shorter diameter and length when longer milling times were applied. The mechanical pre-treatment influenced the crystallinity and crystal sizes of the CNFs as the amorphous regions were degraded and removed.

Particle Size Distribution of Grinding Mill Products
The ball load was 455 stainless steel balls one inch in diameter, having a total weight of 30 kg. The particle size distribution was observed after 20, 40, 60, 80, 100, 150, 200 and 300 ball mill revolutions. The energy input was calculated from the net torque (corrected for the torque for the empty mill) and the number of revolutions.
