TAKRAF Tube Conveyor System
A tube conveyor (pipe conveyor or Japan Pipe Conveyor) resembles a conventional conveyor at the tail end where the material is loaded. From here, the open belt then passes through a series of transition idlers that shape the belt to form a tube for the length of the conveyor. Just prior to the head end, the encapsulated belt passes through another set of transition idlers to open up and allow conveyed material to be discharged in the standard manner. On the return side, the belt is again formed into a tube shape.
1. Environmentally friendly
Tube conveyors are becoming increasingly popular, especially in environmentally sensitive and built-up areas, as interactions between the environment and conveyed material (such as dust emissions and water absorption due to rain or snow) are eliminated by encapsulating the material while in transportation. Valuable product is also protected from theft along the conveyor path.
2. Curved and steep incline conveying
Compared to typical belt conveyors, tube conveyors have very small curve radii, while the tube shape allows the conveyor to curve horizontally as well as vertically. This very flexible conveyor routing often means that a single tube conveyor can replace several conventional belt conveyors, reducing:
- Requirements for multiple transfer points and drives that involve costs, space and power to lift product at repeated transfer points
- Product degradation and dust generation at transfer points
- Costly chute liner replacements
Increased friction between the tube shape of the conveyor and material also makes steep inclines possible – generally up to around 50% steeper than what is possible with a conventional conveyor. This means that:
- Overall length of conveyor system may be reduced
- Plant footprint can also be reduced with further cost savings
