Separator is produced in accordance with third category of GOST-15150 (IEC 60721-2-1; IEC 60068-1), climate version U for internal market and export to temperate countries. However, separators have to work reliably in operating regimes at a temperature from 10 () degrees below zero to 40 () degrees above zero, relative moisture 80% with average annual temperature of 15 () degrees above zero, atmospheric pressure from 650 to 800 mm Hg (86,6÷106,7 kPa).

Structure and Functioning


At the front wall of screen body electric motor with drive pulley is installed, which through the V-belt transmission rotates the pulley with unbalanced weight fixed on it, which provides a circular motion of the screen body. The pulley rotates freely on the bearings, which are mounted on the axle pressed into the traverse. Bearings are closed with covers. Bearings greasing is provided by gun through oil feeder. The frame consists of the front and back pillar, which are connected together by side walls. At the front pillar nozzles for product supply to separator are installed and equipped with inspection ports. Aspiration channel serves for extraction of light impurities from the product. It consists of the housing inside which movable wall is installed. Handle rotation provides shifting of lower and upper parts of the movable wall.


Air consumption is regulated by throttle valve via hand lever. Movable wall is made of transparent material (or with inspection window if the wall is nontransparent) to observe separation process. Feeding roller is designed for uniform feed of product to aspiration channel. From above, on the channel housing adapter for connection to the air duct is installed.


Operation concept of the separator is as follows. Product through the inlet nozzle flows to the feeder, where it is distributed over the entire width of the feeder and directed to the division device, where product is divided into four equal flows and transferred to the body sections.


ATTENTION! To avoid body misalignment in operation, it is necessary to ensure a constant equal supply of grain to each flow.


The machines body circulates that impacts the product to shift over the screen followed by assortment. Coarse impurities are removed from the separator through the trays 12, mixture of grain with fine and light impurities is transferred to the lower screen frame through sorting screen. Fine and light impurities that have spilled through lower screen, fall to the bottom of separator, and are removed from the machine through the trays. Grain, cleaned on screens from coarse, fine and light impurities, enters to the receiver of the aspiration channel, and then, using the roller, uniform flow is supplied to the aspiration channel, where product is intensively blown off by the air flow. Completely cleaned grain is removed from the machine. Air from the body and aspiration channel is transferred through air ducts to the cyclone for cleaning from aspiration foreign matters (impurities).


Separators can be applied both for pre-cleaning (receiving cleaning process) and main cleaning (industrial cleaning process) depending on screens type. To clean the grain from impurities that differ by dimensions different screens, corresponding to shape and size of dominant crops and foreign impurities, can be applied: with circular, elongated and triangle holes. Capacity of the separator reduces with increasing of grain moisture and impurities content.


ATTENTION! To prevent arching of tailings on the body bottom plate during sunflower cleaning, it is necessary to remove the protective layer of the primer coat on the inner surface of the bottom plate.

 

ATTENTION! Screens selection is carried out by the consumer at worksite depending on feedstock and its characteristics (moisture, impurities content, grain particle size etc.) for the purpose of obtaining the required cleaning standard.
