Achkevych O. Justification parameters of the mixer drum feed additives

The thesis is devoted to substantiation technologies feed production on farms in the manufacture of the components of the mixed additives before mixing with grain feed and investigation process of the drum mixer, which allows increasing the nutritional value of feed. On the basis of existing technologies preparation of animal feed mixing sedate invited to perform with a combination of feed components are similar in number to the total mass portions mixture feed in separate groups with sequence acquisition groups ranging from smaller content. Analyzing hardware mixing dry feed and their compliance with the mixed reception of high uniformity components offered constructive scheme drum batch mixer type cylindrical chamber symmetry axis of which is shifted relative to the horizontal axis of rotation. Calculating the weight of the impact on cost minimization mixing process indicators suggests feasibility study criterion uniformity mixture feed. Analytical studies helped to identify functional relationships that describe the mixing process at different stages of his conduct and justify zone issues for experiments. As a result of experimental studies conducted in accordance with generally accepted and developed techniques defined parameters and modes drum mixer, which provides technological reliability of process and necessary even distribution of components in mixture feed. The production test and economic calculations show the feasibility of the technology and developed stepwise mixer on livestock farms.
