At that, in order to increase screening efficiency, the drive mechanism is made in the form of several, at least three cylinders with movable stocks passing through their central hole and fixed in elastic toroids. Toroids are filled with fluid medium providing pneumatic control of back-and-forth- movement in cylinders. |

Invention relates to agricultural production, particularly, to mechanisation of post-processing of whatever seed in compliance with their elasticity. Proposed device comprises bin with proportioners and seed slotted distributors arranged at working sections of reflection surface, intake chambers with separation baffles and adjustment deflecting shutters mounted at top edges of the latter. Reflection surface is composed of flexible endless belt tensioned around at least two cylindrical parallel revolving pulleys. One of the latter is coupled with drive to make a driving pulley. Axes of said pulleys and horizontal sections of reflection belt are deflected from horizontal through the angle varying from 20 to 35 degrees. Proposed device can feed material to be separated on belt sections deflected from horizontal. Cleaners removing stuck particles from reflection surface are located outside of material feed area. |

Method and device for analysis and separation of grain For rapid analysis of grain amount and separation of grain to batches based on one or more amounts of grain parameters the optically dense grain layer is fed continuously through on-line measurement zone, the amount of grain is analysed according to irradiating light on the grain layer, and the light is reflected from the amount of grain, passing through on-line measurement zone, and the light reflected from the amount of grain for providing the spectrum of the amount of grain is recorded, the spectrum is converted into the parameter value of grain or each parameter value of grain, and the grain is separated to batches by sorting the grain amount based on the parameter value of grain or each parameter value of grain. The grain is separated on-line, i.e. during operation of the device, on the basis of the parameter value of grain or each parameter value of grain. |

Post sorting machine with mail recycling device including tape with webs Invention relates to post sorting. Proposed machine comprises sorting collectors to accumulate the mail items. Note here that said collectors are arranged on one straight line in definite lengthwise direction. Note also that this machine comprises additional mail recycling device to recycle the main accumulated in aforesaid collectors. Said device comprises moving belt 40 to displace along sorting collectors and carrying webs 41, 42 making cells 4a, 4b, 4c located opposite said sorting collectors. Note that every said cell allows collecting the mail picked up from appropriate sorting collector. |

Method of detaching buckwheat from wheat seeds Invention relates to agriculture. Proposed method comprises seed processing at bar and sorting screens with oblong holes, in air aspiration channels, cockle cylinder and air sorting table. Larger buckwheat seeds as major impurities are extracted at said bar screen with oblong holes. Buckwheat seeds as short impurities are extracted at cockle cylinder with mesh diameter of 1.05-1.10 of buckwheat seed maximum length. Working edge of cockle cylinder flute is arranged at 45°-55° to its horizontal diameter. |

Method of separating mineral contaminants from calcium carbonate rocks by x-ray sorting Invention relates to separation of mineral contaminants from calcium carbonate ores of sedimentary and metamorphic origin, said, limestone, chalk and marble. Proposed method comprises grinding and sorting calcium carbonate rocks to particle size 1 mm to 250 mm by means of appropriate device. Said device is located downstream of detection zone and controlled by computer-based estimation device in response to sensor signals obtained on radiation of radiation into flow of said particles. Note here that said radiation is emitted by X-ray source and recorded by, at least, one sensor. Note here that X-ray radiation passed through, at least, two filters with respect to power spectra. Said filters are arranged upstream of, at least, one sensor and sensor lines with multiple individual pixels positioned across the flow of particles. Note also that sensor line is intended for every of at least two filters. |

Sieving surface attachment and its application Invention relates to adapter system for attachment of sieving surfaces to jigging screen. Attachment of sieving screen to jigging screen wall comprises insert fitted at screen wall and adapter secured to insert at required height. Insert has some parallel grooves to interact with several ribs on adapter. Grooves and ribs are arranged on sides of the insert and adapter to face each other in fitting. |
