The hammer mill uses a screen of various hole sizes to maximize the residence time in that grinding zone until the particle has reached the desired size. The attrition and turbo mills do not use screens, they depend instead on the gap width between the rotating and stationary parts of the mill in order to control the resultant particle size.

Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134–141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].

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 ...
