Portable Spiral Feeder

Customized for your application

Convey more for less with the new AFC PORTABLE SPIRALFEEDER

With an innovative screw design, the AFC Portable Spiralfeeder combines the low cost and reliability of our Spiralfeeder™ with the high capacity flow of pneumatic conveyors. Get 50% more material flow than traditional screw conveyors of equal size — or use the Portable Spiralfeeder as a less costly alternative to a vacuum and other similar conveyor systems.

Why choose a spiral conveyor over a vacuum or pneumatic model?

What is it

The Automated Flexible Conveyor portable spiralfeeder system is one of the most versatile pieces of equipment that is designed and manufactured at our facility. Each piece of equipment is custom engineered to the clients exacting specifications. Built around and based on our spiralfeeder platforms, these self-supporting rolling chassis, offer a level of manufacturing flexibility that cannot be duplicated.

The Hopper or charging inlet is rigidly mounted on the base portion of the portable chassis. The drive- adapter which consists of a motor, gear box and outlet adapter is rigidly mounted and suspended by the drive support section of the portable chassis.

How it works

The spiral which is coupled to the drive adapter moves the material, by rotational displacement, from the charging inlet en-masse, up the outer tube and discharges out the top of the outlet adapter. Rotational speed, diameter and pitch of the spiral, along with other key dimensional factors, define the overall performance of the spiralfeeder system.


  • Ergonomic design puts the operator at the correct loading height.
  • Minimal assembly required
  • Dust tight operation
  • Reduces costs by reallocating equipment resources to other production areas

Construction Features

  • Safety grate installs with just one mounting tab.
  • Fully welded construction
  • Complete electrical wiring when optioned

Automatic Operation

When properly optioned and equipped, the portable spiralfeeder can run in a full manual/ operator mode as well as a full automatic mode.
