BLTWORLD extends bulk handling solutions to include dust-free, contact-free conveyor belt skirting system for reduced explosion hazards and no material spill


New to the range of bulk handling systems from BLTWORLD, is the contact-free AirScrape® conveyor belt skirting system, which significantly reduces material spill, dust formation and explosion hazards at transfer points and other critical sections in the conveyor chain.

Because this system hovers freely above the conveyor belt, skirt friction and belt damage is eliminated and service life is extended.

“The AirScrape system – which encompasses inward facing, hardened-steel diagonal blades – operates according to a new principle where it hovers 1-2 mm, on the left and right side above the conveyor belt. These blades deflect larger particles inwards, while using the air-flow of the conveyor belt and conveyed material to create an inward suction, flowing any dust and fine particles back into the product flow,” explains Ken Mouritzen, managing director, BLTWORLD. “Through these diagonally fitted plates and the speed of the running belt, air is drawn from the outside inwards. As a result, neither the dust nor material can escape.

“Conventional skirting is pressed against a conveyor belt to keep dust and material in the middle of the belt, but after a period, wear of the skirting and belt can be so severe, that material and dust escapes. Material spillage at transfer points needs to be removed and regular maintenance of belt skirting and transfer points is necessary.

“With the AirScrape dust-free and contact-free, side sealing system for belt conveyors, there is no skirt contact and therefore no belt wear or damage. Motor power requirements are reduced as there is no belt-skirt friction and because there is continuous skirting with no gaps, product loss is minimal.

“Studies show, that even three years after installation and with continuous use in harsh conditions, the AirScrape system hardly shows any signs of wear. Operational costs are also reduced because there is no need for spillage collection, regular maintenance, or replacement parts.”

This system is available in pairs of left and right hand 2 m, inter-connectable pieces, to form any required length and is available in two different base widths of 90 mm and 60 mm, to suit various belt widths and chute sizes. For flexibility on site, this system is completely extendable.

AirScrape is fitted using spacers, floating the blades just above the belt and is attached to the outside of the chute by utilising existing skirt clamps or a simple bolt and nut system. It is longitudinally adjustable to follow the contours of conveyor belt rollers and the belt trough angle.

This durable system consists of non-flammable and anti-static Polyurethane materials and blades made from Hardox/ Stainless Steel. FDA-approved materials are also available for specific conveyor handling applications.

This system – designed and manufactured in Germany by ScapeTec Trading, to the highest quality standards – is available from BLTWORLD throughout Africa and the Indian Ocean Islands. The BLTWORLD team provides an assessment and solutions service for planning and implementing each project. Correct installation of suitable equipment, ensures cost efficiency, optimum performance and safety, reduced risk of breakdown and extended service life of the conveyor system.
