BSH-100

Screen grain cleaner and separator BSH-100 is designed both for pre-cleaning (receiving cleaning process) and main cleaning (industrial cleaning process) of heap of chaff and grain (wheat, rye, oat etc.), groats and legumes, industrial and oil crops from light, coarse and fine impurities, foreign grain and foreign matters that are differ by geometrical dimensions and aerodynamic qualities, and are separable by air flow and screens. The aim of such operations lies in reduction of impurities content in stocked seeds in accordance with criteria specified by Regulations for technological processes at the grain elevators, flour mills, groats mills, and compound feed mills and by other normative documents.

There is no need to advertise the machine which is a long established veteran with worked out design. New customers may learn about BSH-100 from their colleagues, neighbors, partners who have been using it for many years. They learn about their real capacity and purification efficiency, reliability and unpretentiousness, easy servicing and maintainability, and this is the best advertisement.


If its capacity is enough for you, BSH-100 will be the best choice. Screen grain cleaner and separator BSH-100 has no competitors among analogues in accordance with technological process by the price-quality ratio.

Notes* Technical capacity specified on line 1 is referred to the cleaning of feedstock wheat with volume weight 760 kg/m3 and impurities content (seeds of weed and cultivated plants):


  • for pre-cleaning up to 15% with moisture max. 20%;

  • for main cleaning under foreign impurities content max. 3% with moisture content max. 15%. 


With increasing of above mentioned norms of impurity and raw material moisture, separator technical capacity reduces by 2% for every percent of impurity increase and by 5% for every percent of gain in moisture. 


For cleaning of other plants, different from wheat, the capacity reduces in the following way:


  • for rye and corn by 90%;

  • for panic grass and barley by 80%;

  • for buckwheat and oat by 70%;

  • for sunflower by 50% of rated. 


Distinguishing features of BSH-100 from the analogues in accordance with technological process


  • Balance between screen frame mesh size and size of screen cleaners (screen cleaning rubber balls) for more effective cleaning of screens from trapped debris.


  • Access doors at the body side frames and roof for regulation of feeder counterweights and visual monitoring of cleaning process.


  • Quick-detachable doors at the separators body for easy cleaning and servicing of the machine.


  • Advanced repairability due to easy accessible bearing blocks.


  • A wide variety of aspiration equipment: aspiration channels with aspiration system, aspiration chambers with closed air circuit, feeder with possibility of connection to the aspiration system.


  • Separator is equipped with metal frames which design allows significantly reduce physical and time expenditures for screens replacement. Moreover, metal frames are more wearproof than wooden frames, especially in the environment with high humidity and for cleaning of grain with high moisture content.


Structure and Functioning


Main units and parts of the machine are shown at pic.4b: frame 1, body 2 with screen frames 3, drive 4, traverse 5 with balancing mechanism and etc. in accordance with specification.


The body is suspended to the frame by flexible suspensions.


Screen frames 4 are installed in the body (pic.10) by slideway railings 9, fixed on body side frames, and fixed rigidly by clamps 7.


Frame structure is divided into meshes by long and cross baffles, where special rubber balls for cleaning of screens from trapped debris are placed.


At the front wall of screen body electric motor with drive pulley is installed, which through the V-belt transmission rotates the pulley 7 (pic. 12) with unbalanced weight fixed on it, which provides a circular motion of the screen body. The pulley rotates freely on the bearings 5, which are mounted on the axle 9 pressed into the traverse 8. Bearings are closed with covers 4 and 6. From the top at the front side of the body nozzles 7 and 8 (pic. 4b) are arranged for supply of sorted product into the body. There is also a distributing trough 9 for equal distribution of the product along the width of screens.


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 windows. Nozzle for connection to aspiration network is fixed at the back pillar. In order to prevent possible body impact on frame in the moments of start and stop, the limiter 15 with a rubber bumper is fixed on the lower back of the frame connection. For this purpose there are also two rubber limiters fixed on the front pillar of the frame. 


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.


Inlet box 19 with tray is designed for uniform feed of product to aspiration channel. From above, on the channel housing adapter 20 for connection to the air duct is installed. Collector 17 is installed under the channel for cleaned grain removal.


Distributor 8 is designed to divide the feedstock into two identical flows that ensures an equal distribution of grain along the width of separator screens. Grain distribution is provided by weighted slide valve. The uniformity of grain flow is regulated by weight motion on stud bolt.


Operation concept of the separator is as follows. Product through the inlet nozzle flows to the distributor 8, where it is divided into two flows and transferred to the body section by nozzles 7.


The machines body circulates that impacts the product to shift over the screen followed by assortment. An apron in the body reduces possibility of grain removal to rejects.


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 upper 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 tray 13. Screen angles 8˚ upper screen, 7˚ lower screen.


Grain, cleaned on screens from coarse, fine and light impurities, enters to the receiver of the aspiration channel, and then, using the tray, 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 through the bottom collector 17.


Air from the body and aspiration channel is transferred through air ducts to the cyclone for cleaning from aspiration foreign matters (impurities).


Recommended installation diagram of separator in set with aspiration equipment please find in the attached document.


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. Recommended size and type of screens please find in the table below.


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.


More clearly you can get to know the equipment by visiting our production or installed separators in the convenient for you region.
