QUALITY CONTROL METHOD AND MIXTURE PERFORMANCE Dispensers and mixers

摘要

A method for checking the quality of the mixture and the efficiency of dispensers and mixers, comprising determining the number of samples, minimum weight of the sample, sampling the mixture, finding a key component concentration in the sample, calculation coefficient mixture inhomogeneities, characterized in that the mixture is introduced into a known amount of core component representing a foamed polystyrene granule fraction of 0.8-1.2 mm, and its amount is 2.1% by weight of the blend, then at specific intervals selected blend sample dried at 105 ° C and weighed, and the drying process grain Polystyrol swells, making it easy to separate it from the sand component and then calculate the percentage of granules in each sample and variation coefficient is calculated by the formula: where x - average content key component in the mixture,%; x- content key component in each of the samples,% ; n - number of samples analyzed, and by comparing the predetermined value key component concentration and the measured average content key component of x in the samples is determined quality components dispensing the mixture, and the computed value Vc for determining the quality of mixing.
