Ball milling smalltest

The cryogenic milling, tested in terms of plastic-rich fluff density, grinding time and feed size, was found to reach an acceptable final particle size (81–98% of particles at 250 μm) to allow total digestion and accurate and repeatable elemental analyses after a grinding time of between 27 min and 2 27 min (iterative two-step process

    Ball Mill Loading - Wet Milling - Paul O. Abbe

    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%
