Hammer Mills for Particle Size Reduction

In this case, particle size reduction provides the feedstock with the smaller particle size needed to create a pellet of optimum strength. How Hammer Mills Work . FEECO hammer mills utilize a central rotating shaft, fitted with several “hammers” affixed to pivots on the shaft. As the shaft spins, the hammers are swung via rotational energy, causing them to collide with the material ...

Particle size reduction by a hammer mill I: Effect of ...

A new particle size reduction constant, k, is proposed as a result of a linear relationship between dx and output screen size, dss. As dss decreases, the PSD range of milled particles narrows; as mill speed increases (approximately 5000 rpm), dx decreases. The decrease is of a greater magnitude for larger dss (2 mm) than for a smaller dss (1 mm). At low speeds (approximately 1000 rpm), the PSD ...
