Physical characteristics of mixed feeds and original ingredients after mechanical treatment

Abstract

This article highlights the experimental research results
on physical characteristics of mixed feeds and original
ingredients after mechanical treatment. Absolute dry
matter (DM) density was tested in wheat, corn, barley,
soy-bean, cake, rape seed meal and bran. Inner friction
coefficient and repose angle were computed. The
experiment resulted in grinding module impact on inner
friction coefficient and repose angle. Total dry matter
value ranges from 1,35 up to 1,47g/cm³ for the various
wheat sorts in particular. Inner friction coefficient forms
0,51 by 2,3 mm grinding module value and 42° repose
angle for mixed feeds. Inner friction coefficient equals
0,67 and 43° repose angle by 1,76 mm grinding module
value for complete feeds.
