The tested designs of the hammer mill differed mostly in the shape of the hammers. A characteristic shape indicator was the hammer angle (α). In the experiment, the design of a standard rotor (α = 0°) was compared to a new design (α = 35°, 45°, and 55°). Statistical analysis of the experimental results was carried out using self ...
