BLTWORLD
works closely with ScrapeTec, to offer diverse industries in Africa advanced solutions
for conveyor systems used in the handling of abrasive materials with excessive
dust.
“AirScrape®,
DustScrape, TailScrape and SpeedScrape products, which encompass the latest
technology, have been developed by ScrapeTec, to provide
dependable solutions for specific problems – like dust, spills and
contamination – at the transfer points of conveyor systems,” says Ken Mouritzen,
managing director, BLTWORLD, distributors for ScrapeTec in
Africa and
the Indian Ocean Islands. “These highly-efficient systems prevent
dust formation, reduce material spill, enable thorough belt-cleaning and minimise
the risk of explosion at critical sections along the conveyor route and at transfer
points.
“Although
conventional dust prevention side-seals do reduce conveyor problems in the
short-term, they quickly wear-out as a result of friction and can also damage
the belt of the conveyor during extended periods of use.
“Scrapetec’s
robust systems, which are virtually maintenance-free, extend the service life
of conveyor belts and reduce cleaning requirements of the entire conveyor
system. Apart from cost-efficient operation, these products also contribute to
occupational safety, environmental protection and safety, by minimising dust
generation and contamination.
“Correct installation of
this highly-efficient equipment ensures optimum performance, reduced risk of explosion,
low maintenance and extended service life of the conveyor system.”
The contact-free
AirScrape conveyor belt skirting system is a highly-effective side seal that
lies over the conveyor belt, without contact, and creates negative pressure on
the belt, due to its specially-designed lamella structure. Because this system hovers
freely above the conveyor belt, skirt friction and belt damage is eliminated
and service life of every component of the conveyor is extended.
The AirScrape system encompasses
inward facing, hardened-steel diagonal blades and 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. 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.
A
dust-free and contact-free side-sealing system for belt conveyors avoids this problem, as
there is no skirt contact and therefore reduced belt wear. 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 five
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
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.
The TailScrape system
enhances performance of the AirScrape, by sealing the transfer tail
in the rear area and also works according to the Venturi concept, to prevent
dust generation and material spills. The intelligent blade structure on the
underside of the system, creates negative pressure in the conveying area,
preventing the escape of materials. Dust is kept in the material flow by air
intake.
TailScrape is mounted
precisely to the existing AirScrape system, so that it seals the transfer to
the bend, averting dust generation and material spillage, also reducing the
risk of explosion.b metal sheet is used in the rear area of the transfer, matching the contour of the belt trough and installed approximately 20 mm from the belt. The TailScrape is shortened to the distance between the two AirScrapes mounted on the side and bent to fit the trough. The TailScrape is fixed and adjusted to the sheet by means of slotted holes and lifting elements, allowing almost no gap and no contact with the belt.
The TailScrape system is
available in small, medium and large designs, suitable for all belt widths, to perfectly
match the AirScrape variants. Because the TailScrape system also operates
without contact to the conveyor belt, there is no belt or skirting wear. This
system, which can be operated permanently with minimal maintenance requirements,
also extends service life of conveyor components.
For production areas with
excessive dust generation, BLTWORLD recommends installation of the DustScrape.
This dust emission prevention system comprises a filter cloth, support arches
and skirts, arms to hold the system above the belt and a rubber curtain to
eliminate further dust development – all sized to specific requirements. This
system is easy to install and can be retrofitted to existing conveyors, for
continuous operation and for extended periods.
The
durable filter cloth – which retains dust particles created by conveyed
materials, while remaining permeable to circulating air – is available with
different qualities, including anti-static features, for specific applications
– for example, in underground mining.
The
highly-effective, energy-free DustScrape dust emission prevention system, complies
with most new dust prevention guides and prevents health and safety issues
on-site. This system also minimises product loss, by effectively preventing
material from being blown into the surrounding environment.
The SpeedScrape secondary
belt cleaner design is based on the inclined and staggered positioning of
Tungsten blades, which increases the scraping surface to as much as 150% of the
conveyor belt width. This high-performance system allows scraped material to be
easily discharged.
The maintenance-free
tensioner system adjusts the blade pressure to the conveying condition,
ensuring blades are pressed onto the belt, with optimum pressure at all times
during operation. Low stress on the belt reduces damage and wear. The flexible scraping
assembly is able to swivel into a lower position for reversible operation. Durable
scraping blades are manufactured from a high alloy and are designed to
re-sharpen automatically, by scraping against the belt.
These advanced conveyor
belt systems – which meet stringent quality, safety and
environmental standards – are available directly from BLTWORLD, which provides an
assessment and solutions service to customers in diverse sectors, for planning
and implementing projects. A technical advisory and support service enhances
performance of every system.Suggested captions
