PIPE CONVEYORS
The pipe conveyor overcomes several of the problemscommonly associated with conventional conveyors,
e.g. spillage of material, belt training, limited angle ofincline, horizontal curves and multiple flights.

THE PIPE CONVEYOR
The conveyor resembles a conventional troughedconveyor at its tail end where the material is loaded. Theopen belt then passes through a series of transition idlersto form a pipe shape, which is maintained for the lengthof the conveyor.Just before the discharge pulley, the belt opens up againand allows the material to be discharged in the normalfashion. On the return side, the belt is again formed intoa pipe shape.
SERVICES AND TECHNICAL BACK-UP
Pipe conveyors are offered as turnkey installations, withthe design done in-house by Tenova TAKRAF engineers,backed up by dedicated spares and after sales serviceteams.
TRACK RECORD.
About 60 Pipe Conveyor systems have been installed.

PIPE CONVEYOR CHARACTERISTICS
Totally Enclosed Conveying
Material being transported by a pipe conveyor iscompletely enclosed by the conveyor belt for the majorportion of its travel. This has several benefits, including
environmental pollution is minimised as dustgeneration and en route spillage are eliminated,the product is protected from outside contamination,andvaluable product is protected from theft along theconveyors path.
Steep Inclined Conveying
Increased friction between the material and the pipeshape of pipe conveyors makes steep inclines possible,generally 50 % steeper than a conventional belt conveyor.This means that
the overall length of the conveyor system may bereduced, andplant footprints can be smaller with further costsavings.
Minimal Space Requirements
The pipe conveyor is narrower than a conventionalconveyor of the same capacity and uses less floor space.
Return Belt Conveying
The return belt is also formed into a pipe shape and can,in special circumstances, transport material. This offerscost advantages.
Curved Transport
The pipe shape of the belt permits the conveyor to curvehorizontally as well as vertically. A single pipe conveyorcan thus replace several conventional belt conveyors,reducing
the need for multiple transfer points and drives thatrequire more space and cost,power required to lift the product at repeated transferpoints,degradation of the product and dust generation attransfer points, andcostly chute liner replacements.
STANDARD SPECIFICATIONS
The table below shows indicative capacities of the pipe conveyor.Belt speeds indicated are nominal, based on selected idler sizes.Belt speeds and transport volumes can, however, be increasedwithin accepted design limitations to cater for the customersspecific needs.
