Development Of Sie Reduction Equations For
The wood chips were successively ground in a hammer mill using screen sies of 25.4 10 6.4 and 3.2 mm. The input power and the flow of material into the hammer mill were recorded continuously. The recorded power input vs. mean particle sie showed that the Rittinger equation had the best fit to the experimental data.
