Pipe conveyors are an evolution of traditional belt conveyors.
These machines consist of loading points, drive and tail heads identical to standard belt conveyors ones, but have a different 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 pipe 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 every type of material leakage, pipe conveyors can make curves both horizontally and vertically, running along winding paths and going round obstacles and existing structures.
