FEATURES GRINDERS - MIXER WITH OPTIMIZATION OF PROCESS PARAMETERS

The existing constructions of continuous-running fodder choppers-mixers for small cattle were investigated in the article. The analysis of advantages and disadvantages of existing choppers was conducted by abstracting effective areas of their application. It was established that it was inappropriate to chop concentrated and rough feed simultaneously, because the fibrous materials of rough feed reduce the impact force of unmilled grain with the working surface of the chopper. Moreover, the food making aggregate must be equipped with process automated facilities. The basic models were determined, which improvement allows increasing the efficiency of mixing rough, concentrated and succulent feed. In most cases while technological optimization processes in animal industry it is advisable to use the second-order design, because the processes are complex and the significant factor coefficients of regression may appear in the model which have to be raised to second power.
