Accuracy of discrete metering devices in relation with the criterion of formed mixture quality assessment

Abstract

Abstract The article considers the quality indicator (criterion) of the resulting mixture products as a two-parameter function of the metering devices accuracy and the parameter of the final effective mixture (product) application. The first parameter is intermediate and considers the functional characteristics of the single-piece produced an effective dose of a mixture with a given (required) volume or mass. The second parameter reflects the results of the final task to use mixture products or a product in total. Such a technological approach is advisable when it is difficult to describe the process of forming the mixture quality by one parameter, or when taking into account a large number of factors affecting the mixture quality obtained, and the result becomes biased. Then the second parameter is worked into the structure of the criterion for quality mixing assessment, taking into account the ultimate goal of using a mixed product or the product this mixture is included into. In this case a significant number of factors affecting the mixture quality and the effectiveness of its use according to two generalized parameters can be considered. The first typical classical parameter that affects the quality directly during mixing is the accuracy of the constituent component dosing. The second output parameter of the finished product comprehensively describes the efficiency of its use. The final parameters of the mixtures application can be determined experimentally, analyzed, and they, in turn, integrally cover the entire spectrum of many diverse factors affecting the mixture quality and the effectiveness of its use.
