ethod for separation of loose materials // 2645321
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.4 cl, 5 dwg

ethod and device for measurement of inertia force acceleration at shear flow of layers in granular material // 2461431
FIELD: measurement equipment.SUBSTANCE: invention refers to technical measurements, and namely to measurements of inertia force acceleration value at relative shear of layers in granular material. It can be used in agricultural industry and processing industry, where grain cleaning machines operate based on use of layer-by-layer shear flow of grain medium under action of inertia forces on screens and sieves. Measuring method of inertia force acceleration at shear flow of grain contained in a trolley with application of marks from contrast material on cross section of grain body for determination of shear value of each grain layer and the whole grain body relative t trolley bottom, movement of trolley on rails and its braking. Recording of trolley movement parameters at braking moment is performed by means of a cassette with photosensitive paper, which is installed on its lateral side and onto which the light falls from two fixed lamps through two holes in a curtain. One of the lamps fixes on photosensitive paper the braking path and the other one - time intervals. Braking of granular material - trolley system is performed using coil spring. Activation and deactivation of lamps at braking moment is performed automatically at opening and closing of contacts located on fixed stop. Method is implemented by means of the device containing a trolley having the possibility of being moved on rails under action of falling weight, photoelectric device for measurement of kinematic movement parameters of granular medium - trolley system at braking moment, which is made in the form of a cassette with photosensitive paper, which is fixed on the trolley side, and two lamps one of which fixes braking path and the other one fixes time intervals on photosensitive paper.EFFECT: higher measurement accuracy of parameters of shear flows in granular medium, which are required for adjustment of sorting machines for optimum operating mode.4 cl, 5 dwg

Loose material classifier // 2341338
FIELD: engines and pumps.SUBSTANCE: loose material classifier incorporates intake bin, running cylindrical shafts fitted to form a sizing slit, sized material receptacles. The aforesaid shafts represent and upper shaft integrated with a drum, a pusher intended for preventing the sizing slit clogging and a power shat with a feed drum, both shafts running in one direction. The upper shaft runs 2 to 3 times faster than the lower one. To allow material move along the slit and to prevent clogging the later, the drums are furnished with multi-start threads with slot width making b=(3-4)l, where l is the slot length and depth making h= (0.3 to 0.5)l. The angle formed by the horizontal pane and the shafts axes plane varies from 30 to 60 degrees.EFFECT: higher efficiency of sizing and lower wear of components.2 dwg
