EN The cut size determination on the basis of proposed matrix model of classification process in a centrifugal air flow classifier with a fluidized bed is presented using matrix model. The presented methodology of cut size determination is based on the precise measurement of the total mass of fed material and coarse product in experimental tests. Knowledge of the feed particle size distribution is also required. Considered classifier is a part of the fluidized bed jet mill. The presented cut size determination will allow to optimize mill work and prediction of particle size distribution of the classification products.
PL W artykule przedstawiono metodykę wyznaczania rozmiaru ziarna granicznego procesu klasyfikacji w odśrodkowym klasyfikatorze przepływowym z warstwą fluidalną przy wykorzystaniu modelu macierzowego. Przedstawiona metodyka oparta jest na dokładnym wyznaczeniu masy nadawy i gruboziarnistego produktu klasyfikacji na podstawie badań eksperymentalnych. Wymagana jest także znajomość składu ziarnowego nadawy. Rozpatrywany klasyfikator stanowi część fluidalnego młyna strumieniowego. Wyznaczenie rozmiaru ziarna granicznego umożliwia przeprowadzenie optymalizacji pracy młyna i prognozowanie składu ziarnowego produktów klasyfikacji.
