Optimization in work modeling of a mixer

The paper presents a list of indicators used to optimize the working process of rotary machines using the example of a mixer. The shortcomings of polynomial statistical models are indicated and the use of functions which nature of variation corresponds to the theoretical positions is recommended. The theoretical dependencies of the mass of the prepared portion of the mixture, the quality of the mixture, the duration of mixing, the productivity of the mixer, the drive power, the specific energy consumption are revealed, taking into account the uniformity of the mixture. These dependencies and the refinement coefficients that appear in them have the form of power and exponential functions. These functions do not have an extremum, therefore optimal parameters are impossible.
