Hammermill tip speed adjustment alters particle size

Apr 26, 2018· Increasing screen hole diameter decreased (linear, P 0.001) angle of repose (43.9 degrees, 41.3 degrees and 38.6 degrees, respectively). In summary, the particle size range for a specified hammermill screen size can be adjusted through manipulation of the hammer tip speed, which is made possible by the use of motor variable frequency drives.

The impacts of hammer-mill screen size and grain particle

4. The 2.0-mm hammer-mill screen generated an average geometric mean particle size of 794 μm and the 6.0-mm screen a mean particle size of 1405 μm. However, hammer-mill screen size did not influence weight gain or FCR. The 6.0-mm screen size generated significantly higher starch and protein (N) digestibility coefficients in the distal jejunum
