OPTIMIZATION OF SPIRAL MIXER-PIPELINE CONSTRUCTIVE-TECHNOLOGICAL PARAMETERS

The purpose of the study is reduction of mixing concentrated feed (fodder concentrates) energy, respecting the zootechnical requirements for quality of the mixture by using mixers-conveyors. The tasks of the study are to set the functional dependence between the structural and technological parameters of the mixer and process indicators to identify optimal or rational values of mixer parameters providing the required quality and the lowest power consumption of carburetion mixture. The description, constructive scheme and photo of continuous action mixer-conveyor with volute working body are given. The author describes the method and results of experimental studies of continuous action mixer-conveyor. The article deals with the expressions describing the unevenness of mixture and energy stirring consumption depending on the length of the mixing zone, the device performance and the proportion of the controlling component. There are constructed two-dimensional sections of the second order response surfaces. Mixer parameters are justified based on the analysis of mixture unevenness graphs and energy justified options mixer: optimal device performance is about 3.6 t/h; mixer-conveyor is able to prepare dry mix with share of the mixture component - not less than 13% and the length of the mixing zone - not less than 1 m.
