STUDY OF COMBINED FEEDS QUALITY MADE BY HAMMER MEALS AND HORIZONTAL MIXERS

Abstract

The study was made in order to establishing qualitative indexes of combined feeds made by hummer meals MB-22 and mixed by horizontal mixer Himel. Granulometric tests were made by sieving machine AS-300 using 3 plates with 2.5 mm, 1.25 mm and 0.63 mm orifice size and two working mode: continuous and intermittent. Obtained results indicate mixture combined feeds, having a percentage of particles kept on 2.5 mm plate between 4.8% (intermittent sieving) and 5.8% (continuous sieving) suitable for hens like used recipe, being in frame limits indicate by other authors (Popa, 1983). Concerning index of particles average , the estimation indicate to fine granulations to all samples, the results are not concluding because of different orifice size to AS-300, comparing with other authors.
