Fine grinding of polymers in a vibrated bead mill
Moreover, the grinding limit is higher for 45% of beads than for 20%. When the mill contains 70% of beads, the reduced size first increases slowly before decreasing. A very bad mixing of beads and polymer may explain this result. In fact, in a shaker bead mill, the grinding rate is greatly influenced by the mixing state of the bed [8]. On the ...
