Pipe Belt Conveyor (PDT)

Pipe belt conveyor is intended for conveying of loose and pebble materials and works on the principle of the closing of upper and lower parts of belt in a pipe shape and protects transported material against external environment (rain, snow, air humidity, etc). It removes also a usual problem of ordinary belt conveyor, i.e. dirtying of area below the whole length by dust crumbling from the lower face of conveyor belt. Circular shape of belt enables a path line with curves in vertical and also horizontal axis. Maximal temperature of conveying material is up to 150 °C. Pipe belt conveyor is sometimes called as flexopipe.

Dimensions and parameters:

1600 400 350 140
1900 500 460 180

* Q/m3/h at conveying speed of 1 m/s.


  • Parameters data of conveying rate incl. grain size are only mentioned for preliminary information and required anyway technical analysis and calculation.
  • A minimal conveyor axis distance of 70 m is recommended.
  • Belt tensioning is always of gravitation type.
