Present study was aimed to improve efficiency of sieve and screen separators by reducing specific load on a sieve (screen) through preliminary separation of the initial mixture of crushed material on air delivery stage in pneumatic screw classifier. Parameters of grain milling product separation in pneumatic screw classifier using planning of multifactorial experiment and processing of statistical data are presented. We have built pneumatic screw classifier prototype and performed its production check basing on these results. https://www.biotech-asia.org/vol13no2/experimental-study-of-parameters-of-grain-milling-product-separation-in-pneumatic-screw-classifier/ grain processing; pneumo-centrifugal sorting; pneumatic screw classifier; grain milling products
