The mathematical model of the separation process of grain components through a cascade sieve separator with blind stores installed between the blocks of sieves

A mathematical model describing the process of separating the grain materials components through a cascade sieve separator with blind stores installed between the sieve blocks is developed in the article. This mathematical model differs in that it describes the separating process of the components of a grain material through a cascade sieve separator in which blind stores of a certain length are installed on the end sections of each tier of sieves to increase the efficiency of extracting long impurities due to the fact that long particles of grain material after passing into the holes of the above sieve fall not on the sieve, but on the layer of grain material.. Thus, they are oriented by the long axis along the sieve plane, increasing the elimination efficiency of the long impurities.
