The questions of the use of seeds for fodder in animal husbandry and its preparation in the technological line by cleaning seeds from hard-to-separate seeds of weeds are considered. It has been established that general-purpose pneumatic sieve separators, which are usually used for cleaning seeds, remove a significant amount of weed seeds, mineral and organic impurities, but completely remove hard-to-separate seeds, such weeds as, for example: mice, chicken millet, tenacious bedstraw and others fail.
The given data on the use of rapeseed processing products for feed for pigs and cattle, for example, rapeseed cake, is used as part of compound feed, it can increase the productivity of cows and reduce labor losses per unit of production up to 5 ... 14%. It is proposed to purify seeds from difficult-to-separate impurities using a multi-tiered impact separator.
The article presents the modeling of the process of separation of seeds by a percussion separator. The motion of a particle idealized in the form of a material point when it collides with inclined, in the longitudinal and transverse directions, decks of the impact separator is considered.
The theoretical productivity of the impact separator is calculated, which is 8 ... 30 kg / h. for one module. The studies carried out made it possible to determine the design parameters of the multi-tiered impact separator and calculate its performance.
