At any speed

A contact-free conveyor belt skirting system significantly
reduces material spill, dust formation and explosion hazards
at transfer points and other critical sections in the conveyor

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

“The AirScrape system, from BLTWorld, encompasses inward facing, hardened-steel diagonal blades, and operates according to a new principle where it hovers 1-2mm, 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.”

Regular maintenance
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 our 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,”
Ken explains.

This system is available in pairs of left and right hand 2m, 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.

Approved materials
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 ScrapeTec Trading, to the highest quality standards, is available 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.
