    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

    Dec 23, 2013 Size reduction increases as the number of rotations and time taken for ball milling increases. 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
