Grain Cleaning Systems

Grain Cleaning suitable for an extensive range of crops.

Chief Industries UK Ltd can supply a whole range of grain cleaners.The simplest and cheapest of these are the aspiration cleaners that remove dust and light trash, but do not have any size separation. Drum cleaners provide an inexpensive size separation of grain through rotating screens and can be provided, with or without aspiration cleaning. Capacities with this type of cleaner can range from a few tons per hour up to 400tph and are frequently preferred for pre-cleaning grain before drying and entry into a grain store.   

Also available are a range of reciprocating screen cleaners using flat screen decks vibrating forwards and backwards, again with the possibility to incorporate aspiration cleaning in the same cleaner.

This is why a drum grader is requested for precise grading. Accuracy<img style="margin: 10px; float: right;" src="assets/site/images/UK/EAC2004VPeditedsize.jpg" alt="" width="448" height="299" /><br />decreases when grain bounces on a vibrating screen.</p> <h3><br />Reduced vibrations:</h3> <p><br />On an existing light stand, reduced dynamic force allows installation of drum cleaner when a<br />vibrating flat screen machine needs stronger and more expensive installation.</p> <h3><br />Efficient deblinding:</h3> <p><br />Especially for seed cleaning, removal of small or broken seeds with little perforations is<br />important. Drum deblinding of perforations remains perfect, easy to control and keeps high level<br />efficiency. Flat screen cleaners have a bottom screen impossible to check and difficult to<br />deblind because of the thick layer of seed pressing constantly the blinded perforations.</p> <h3><br />Flexible diagram:</h3> <p><br />On a drum, each screen can be used for screening or for scalping, and possibly fit all needs.</p> <h3><br />Variable speed and slope:</h3> <p><br />Increase speed or slope on a flat screen increases bouncing of particules and reduces precision.<br />Because of the continuous movement, these variations are very precise on a drum and can be<br />easily controlled.</p> <h3><br />Suitable for difficult products:</h3> <p><br />Because of this flexibility, a drum is always used to process difficult products (eg. cotton, wet<br />maize, etc) or when an installation must be multi-purpose. Using a similar machine for both<br />precleaning and fine cleaning reduces maintenance problems.</p> <hr /> <p> </p> <h2>Screen Pre-Cleaner</h2> <p>MAROT PN (“Pré-Nettoyeur”) pre-cleaners are designed for simple and quick removal of large impurities and rubble from grain. This is essential prior to drying in order to avoid <br />blockages and unnecessary expenditure in energy. Grain enters into the rotating drum and passes through the screen perforations leaving the large rubble to be rejected at the end. The choice of screen perforation size depends upon the duty and the type of grain to be precleaned. PN 601, 1002, 1253, 1503, 2004, 3003, 4004 and 5005 enable small trash to be rejected at the first screen section. The pre-cleaner has a large screen area and is equipped with a system to keep the perforations clear. Flow rates from 35 to 400 tonnes per hour can be achieved. Aspiration in various forms can also be added.</p> <p><strong>G: </strong><span>Raw Sample</span><strong> - R: </strong><span>Large rejects</span><strong> - A + B: </strong><span>Good grain</span></p> <p><span><img src="assets/site/images/UK/MarotDiagram.PNG" alt="" width="260" height="182" /><img src="assets/site/images/UK/Marotgraph.PNG" alt="" width="860" height="281" /></span></p> <p> </p> <p> </p> [richtext] => 1 [template] => 38 [menuindex] => 0 [searchable] => 1 [cacheable] => 1 [createdby] => 27 [createdon] => 1473779737 [editedby] => 27 [editedon] => 1479889264 [deleted] => 0 [deletedon] => 0 [deletedby] => 0 [publishedon] => 1473793560 [publishedby] => 27 [menutitle] => Marot Rotary Drum Cleaner [donthit] => 0 [privateweb] => 0 [privatemgr] => 0 [content_dispo] => 0 [hidemenu] => 0 [class_key] => modDocument [context_key] => UK [content_type] => 1 [uri] => products/grain-cleaning-systems/grain-cleaning-marot.html [uri_override] => 0 [hide_children_in_tree] => 0 [show_in_tree] => 1 [properties] => Array ( [stercseo] => Array ( [index] => 1 [follow] => 1 [sitemap] => 1 [priority] => 0.5 [changefreq] => [urls] => Array ( ) ) ) [tv.CHA-SectionImage] => assets/site/images/UK/marot11.PNG [idx] => 1 [link] => ) Array ( [id] => 1132 [type] => document [contentType] => text/html [pagetitle] => DENIS NSD Range [longtitle] => DENIS NSD Range - The screen cleaner [description] => The screen cleaner are the fruit of the knowledge and experience of Denis in this field.
