Portable Dust Extractor have got wide applications in the following machines and industries : tool cutters / surface grinders, buffing machines, abrasive cut off machines, diamond polishing machines, carbon dry powder collection, wood working industry, packaging machines, trim collections, etc. It provides clean working conditions, increases operator efficiency and prolongs equipment life. The unit is compact, inexpensive and is continuously rated, making its high cleaning efficiency comparable to units selling at higher price. It is easy to operate and needs practically no maintenance.
Principle of Operation :
The dust generated is picked by a slitted hood in an air steam generated by powerful suction blower. Dust separation takes place in two stages. In the primary stage, heavier particles are deposited into the collection container due to reduction in velocity and change of direction of air. Secondary separation occurs when the lighter dust is deposited onto the fabric by initial impact and diffusion. Hence, its accumulates to form a mat or bed, which in turn acts as filter medium with a fabrics periodically removed from the fabric by the shaker mechanism and deposited into the collection container
