    Nov 16, 2020 The balls to powder ratio (BPR) and powder type were investigated in relation to the particle size. The study showed that the combination of the BPR and powder type affects the particle size result. The optimum of BPR at 12 with the number of balls is 60 pieces, and the filling rate is 10.13%. The result shows that the horizontal ball mill able

    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%

Meshes of larger aperture should be used in sieving to obtain a complete curve of particle size distribution. Some particles were lost when transferring them out of the ball milling, which results in lighter weight obtained after ball milling. References: 1

    Ball milling, a shear-force dominant process where the particle size goes on reducing by impact and attrition mainly consists of metallic balls (generally Zirconia (ZrO 2) or steel balls), acting as grinding media and rotating shell to create centrifugal force. In this process, graphite (precursor) was breakdown by randomly striking with grinding media in the rotating shell to create shear and compression force
