These machines consist of loading points, drive and tail heads identical to that of standard belt conveyors, but have a distinctive conveying section, with a particular shape.
After the loading point, the belt is folded around the material and assumes a tubular shape along the whole length of both upper and return strand.
Special hexagonal idler stations, installed on properly spaced panels, keep the round shape of the belt. Before the drive pulley the belt opens again and the material is discharged in the traditional way.
Thanks to the complete enclosure of the belt, which prevents all types of material leakage, pipe conveyors are capable of both horizontal and vertical curves, negotiating obstacles and existing structures.
The section of a pipe conveyor is smaller than the equivalent belt conveyor, therefore space requirements are minimum and weight of structures and supports are lower. As the material is transported inside a tubular belt it therefore allows for a higher angle of slope of the conveyor: a single pipe conveyor in some cases can replace the combination of belt conveyor and bucket elevator.
FROM EXTERNAL CONTAMINATION
The belt of the pipe conveyor is folded into a dust-tight enclosure, which prevents material leakage and protects from external contamination, including water and moisture.
Maintenance costs are minimised. The idle rollers always work on the “clean” side of the belt thus further improving the already low maintenance characteristics of a standard belt conveyor.
POSSIBLE MATERIAL TRANSPORTATION
IN BOTH DIRECTIONS
Both strands of the conveyor can be utilized for conveying. Import/export conveying lines have substantial advantages from such a feature.
The design of intermediate frames can be optimised in order to obtain long spanned sections between supports. Several solutions are applicable and the most complex long distance conveying situations are affordable, minimising investment costs for the related structures.
NO LEAKAGE OR SPILLS
ALONG THE PATH
The complete enclosure of the transport and return strand guarantees no material leakage, therefore avoiding the need for cleaning.
MORE ENVIRONMENTALLY FRIENDLY
OVER OTHER TRANSPORTATION METHODS
The complete enclosure of the belt and the return strand guarantees that dust and smell emissions are completely avoided along the whole length of the path
ALLOWS BOTH HORIZONTAL AND VERTICAL CURVES
Pipe conveyors allow for both horizontal and vertical curves. Thanks to this characteristic, a single pipe conveyor can replace two or more traditional conveyors, removing the need for transfer points with relevant steel structures, dust control systems, etc.
DUST TIGHT ENCLOSURE
The dust tight characteristic of the pipe conveyor avoids the need to utilize enclosed galleries to protect the external environment.
