Environmentally friendly bulk material transport is possible with tube conveyors.
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.
Compared to typical belt conveyors tube conveyors have very small curve radii. This very flexible conveyor routing often allows a reduction of the numbers of transfer points and opens the possibility for long distance environmental friendly material transport.
- We design, fabricate and supply a wide-range of tube conveyors catering to clients' specific needs and requirements
- Flexible conveyor routing allows for the reduction in the number of transfer points
- Significantly reduced environmental impact due to encapsulation of transported material (reduction specifically in dust emissions)
- No transported material contamination
Customer Project name Maritza East 1 power plant residual transport AES Power plant Maritza East 2010
Tube conveyor at power plant Maritza East
The tube conveyor was selected to transport residual materials (ash and gypsum) from the power plant to the disposal area by two reasons:
- Environmental friendly transport without influencing material and surroundings
- Conveyor routing following the natural terrain with tight horizontal and vertical curves
The tube conveyor is running in eight horizontal curves with 350 m to 500 m radius. To ensure the correct overlap position at the discharge area the patented belt training system (BTS) is used.

Tube conveyor for dry ash removal system
TAKRAF has delivered the complete residual material handling and disposal system including:
- Long distance material transport with tube conveyor
- Transfer tower to feed the dumping system or the emergency stockpile
- Dumping system with shiftable conveyor, tripper car and stacker
- Emergency stockpile with radial stacker
Tube conveyors are very common in residual material transportation due to the encapsulation of the material. Special feature of this project is the ambient temperature of minimum -45 °C combined with a material temperature of maximum 90 °C at the tube conveyor feeding point.
The tube conveyor is running in five horizontal curves with 420 m to 630 m radius. To ensure the correct overlap position at the discharge area the patented belt training system (BTS) is used.
