PST Shaftless Conveyors

Supplier: Recycling Technologies Group

SwarfTech are pleased to announce the latest edition to their suite of technology driven processing and waste recovery systems. PST Conveyors are Sweden’s leading conveyor developers and their shaftless spiral conveyors are taking the world by storm.


PST Spiral Conveyors provide problem free handling for a wide range of materials and alleviate issues such as blockages cause by bridging and binding of stringy and thread-like material. Due to their increased capacity (because the voluminous central shaft has been eliminated) they are also very economical. And if that isn’t convincing enough they are significantly safer than other conveyors because they are fully enclosed and therefore dustless and have no hazardous exposed parts.

Why should you consider using PST shaftless spiral conveyors?

Here are some key reasons why.

  • PST Spiral conveyors can be inclined from 0 - 90 degrees vertical
  • PST Spiral conveyors convey a greater volume / rpm because there is no centre shaft to take up valuable space
  • Threadlike materials do not bind on a centre shaft – because there is none.
  • Fully enclosed and dust free system
  • Long unbroken runs are possible
  • Minimum moving parts – there is only one bearing.

Typical materials that are handled are rejects from pulpers, wood chips, sawdust, pellets, sludge, trimmings, waste, chemicals, plastic granules, powder, foodstuff etc.

The conveyors are maunfactured both as trough and lad as well as tube conveyours depending on the application. They are produced in a variety of materials depending on the particular application required, these include mild steel, stainless steel and acid proof stainless stell.

The capacity range of the conveyors are between 1 - 1000m3/h.


With over 35,000 PST shaftless spiral conveyors now in user throughout Europe it's fast becoming the Number 1 conveyor choice for organisations who want to run with the latest technology.

Spiral Conveyors have a wider application that merely transporting material from A - B. They can be used to separate solid and non floating particles in fluids, in industries such as paper and waste processing.

The PST spiral conveyor will also act as a dewatering press. This is an efficient, simple and reliable press for the dewatering of various materials. It possesses a double function in that it both conveys and dewaters. Examples of normal materials that are pressed are fibres in paper mills, filter rejects in wastewater treatment works, waste in abottoirs and catering services etc.
