Influence of input parameters setting on the operating process of the weighing system

The problem of accuracy and speed of weight dosing of feed ingredients, as well as the material for the production of pellets, remains unresolved. The paper presents the results of experimental studies of the weight dosing system with a screw feeder DH-120. To improve the accuracy and speed of the dosing process, to eliminate subjective errors in the installation; an automatic Schneider control system is implemented. The dosed materials used are different in appearance, physical and mechanical properties, and feed value ingredients: salt, chalk, whole and ground barley grain, sawdust and shavings. Conditionally, at the first stage of the experiment, the input parameters are separated with fixed and variable values. Elements of the experiment planning theory were used to construct the experiment and process the results. The relative error of the weighting is used as the optimization criterion. For the DH-120 auger dispenser, the rational values of the rotational speed of the auger shaft when dosing sawdust and shavings are experimentally established to be 31.24, salts and grains – 28.4, and swept – 34.08 min^-1. Thus, based on the results of the analysis, the significance of the input parameters on the efficiency of the weight dosing system is determined.
