Solventless Mechanochemical Synthesis of Phase Pure Syngenite

Then, the optimal mass ratio of ball to powder in ball mill is 7.5*24/(2.5*17.6)= 4.09 to 7.5*21/(2.5*11.2) = 5.63. References Austin, L. G., Klimpel, R. R., & Luckie, P. T. (1984).

ratio wet ball mill filling

The ball-to-particle filling mass ratio (BPR), defined as the amount of particles and balls placed in the mill pot, plays an important role in controlling the dissipated energy of the particles. Planetary ball mills are one of the most frequently used high-energy mills owing to their structural simplicity and good operability.
