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

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.
