Portable Spiral Feeder

Customized for your application

Convey more for less with the new AFC PORTABLE SPIRALFEEDER

With our innovative screw conveyor 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 bulk 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.

And this conveying system rolls from one area to another!

What is it

The versatile Automated Flexible Conveyor portable Spiralfeeder system is custom engineered to meet exacting specifications based on the materials conveyed, production targets, regulatory environment, and more. Built around and based on our proprietary Spiralfeeder platforms, this mobile system is set on a self-supporting, rolling chassis. Just roll it to the mixer, tank or other point in the process and press start. It offers a level of manufacturing flexibility that has not been duplicated.

The hopper or charging inlet is rigidly mounted to the base of the portable chassis. The drive motor, gear box and outlet adapter are rigidly mounted and suspended by the drive support section of the portable chassis. It’s strong, sturdy, and stable.

How it works

The spiral moves the material by rotational displacement from the charging inlet en-masse, up the outer tube, then discharges the material 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. These factors are considered and tested before production.


  • Ergonomic design puts the operator at the correct loading height
  • Minimal assembly 
  • 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 included as option

Automatic Operation

When properly optioned and equipped, the portable Spiralfeeder can run in a full manual/ operator mode as well as a fully automatic mode. Automatic mode can be controlled by low and/or high level signals. Dry contact inputs can also be integrated into the control logic for external signal interfacing and multi-speed operation when equipped with a variable frequency drive.

Product Variations

  • Mild steel construction
  • Stainless steel construction: T-304 or T316
  • Industrial or sanitary finish
  • Loss-of-weight configurations
  • Hazardous and non-hazardous locations
