Feeders & Gravimetrics

The most effective way to control raw material usage, is to monitor it through a feeder.

Rollepaal’s feeders ensure extremely accurate dosing

  • Offer maximum control, efficiency and savings through continuous loss-in-weight measuring
  • Calibrate the dosages and make adjustments automatically
  • Easy to adjust to a multi-component system, dosing up to six additives at the same time
  • Completely integrated software in the central controls
  • User-friendly
  • Easy to operate and easy to clean
  • Stable in colour additives


  • Rollepaal Direct Mixing (RDM): the next step in processing. PVC resin and the necessary additives can be mixed directly on top of the extruder, meaning no need for a mixing plant
  • Rollepaal Direct Addition (RDA): this unit is mounted on the extruder for constant dosing of hard-to-handle materials in an industrial environment
  • Rollepaal Gravimetric Systems (RGS): control the flow of material to ensure a stable extruder output regardless of fluctuations in bulk density
  • RGSF: a single screw feeder designed for free-flowing materials such as granules and prills
  • RGDF 4: a self-wiping double screw feeder designed for dosing non-free-flowing sticky powders
