METHOD FOR SEPARATION OF LOOSE MATERIALS Russian patent published in 2018 - IPC B07B13/02 B07B13/05 

FIELD: technological processes.

SUBSTANCE: method for separation of loose materials includes feeding separated material onto an inclined endless belt, transporting the material by the belt, material separation into fractions and removing the separated material to appropriate receiver tanks. The transportation and separation of the separated material is carried out at least at two additional levels of inclined endless belts. At each level, the separated material, due to the inclination of the surface of the endless belt, is simultaneously stirred up and moved to the splitters mounted at the bottom of each belt at an angle to the direction of movement of the material to be separated. At each level a part of the separated material, which does not exceed the dimensions of the belt seatings, identifying the size of the separated fraction, is separated from the main stream, captured and removed to the appropriate receiver tanks, and the remaining part of the separated material is directed to the next separation level using trays. The seatings on the endless belts are made of dimensions, which are equal to 0.3-1.2 of the diameter of the material being sorted, while on each subsequent inclined endless belt the seatings are greater in size, than the previous seatings by 20-50%. The seatings on the inclined endless belts are made round, or in the form of elongated ovals. The angle of inclination of an endless belt is equal to 35-75 degrees to the horizon.

EFFECT: increasing the efficiency of the separation of particles of loose materials into several fractions, increasing the separation efficiency and increasing the yield of finished products.
