Compacting shaftless screw conveyor

Shaftless screw conveyors are designed to convey difficult, viscous or fibrous materials that tend to pile up and cause clogging. They are the ideal solution for dehydrated sludge and waste from centrifuges, compactors and mixers. The shaftless design provides the opportunityto transport difficult materials without clogging problems that usually affects a screw welded on shaft.
The shaftless screw was designed for transporting sludge in the water residues sector. Due to its efficiency, it was later adapted for other sectors.
The shaftless conveyors that we use may solve our customers’ issues. Currently, with our technology, it is possible to substitute a traditional conveyor with a shaftless model.

Compacting shaftless screw conveyor benefits

Low operational cost:
  • There are no sealing joints, bearings, or ball bearings.
  • There is no risk of clogging.
  • Fills the container 50% more than the shafted screw.
  • The conveyors can be horizontal, inclined or vertical.
  • Removable bolted cover.
Occupies a reduced amount of space:
  • At one end of the screw the gearmotor is instaled. The other end is free, which allows an axial or angular connection to another conveyor and a direct transfer of the load.
Applications:
  • Municipal (sewage waters and solid waste)
  • Industrial (food industry, chemical industry, pulp, paper and incineration plants, etc.)
Cover:
  • Removable (easy maintenance).
  • Materials: HDPE, Hardox ; Natural Latex.

Screw profiles:
  • Shaftless: closed trough design.
  • Conical exterior edge on the interior edge, apply the stress (compaction/lengthening) to the interior diameter.
  • Peripheral section of the Hardox 400 HB is wear-resistant.
Hygienic:
  • Completely closed and sealed to control smells and leaks.
