FIELD: various technological processes.
SUBSTANCE: proposed invention relates to equipment of agroindustrial complex, in particular, grain processing enterprises, and can be used in agriculture, as well as for separation of granular materials in dressing and chemical industries. Gravitational separator of loose granular materials contains a loading hopper, a feeder-batcher, receivers with branch pipes for collection and discharge of extracted fractions, a working surface limited by an end wall and two side walls. Working surface is installed at an angle to horizon and consists of two cascades: first – receiving surface and sieve for separation of coarse impurities with grooves installed above them, and second – accelerating surface and set of sieves with differentiated by size holes for separation of unused wastes, fodder grain and medium grain fraction and with plows installed above them. Grooves and plows are fixed on the frame of the gravity separator of loose granular materials with the help of brackets with the possibility of adjusting their lower face in height relative to the sieves, and the plows are also fixed with the possibility of adjusting the angle of meeting of their working surface with the moving grain layer. Gravity separator of loose granular materials is made with possibility of operation in modes of preliminary, primary, cleaning and in mode of grain size classifier.
EFFECT: reduction of energy consumption for the separation process, increase of productivity and efficiency of grain separation.
