Cooling conveyors for hydroscopic materials

  • Stainless steel belt instead of perforated plastic belt
  • Suitable for high-temperature polymers that cannot be water cooled due to their moisture absorption

Reduction Engineering Scheer, a global manufacturer of strand pelletizing systems, has expanded its line of cooling conveyors with the introduction of a new Stainless Steel Conveyor (SSC) which cools highly hydroscopic materials during strand pelletizing. The newly designed cooling conveyor is designed for materials such as bio-based plastics, highly-filled metal compounds, along with certain polymers used in the medical industry that are water soluble.

Stainless steel belt instead of perforated plastic belt

The cooling conveyor uses s solid stainless steel belt instead of the standard perforated plastic belt which typically allows water and air to pass through it. The conveyor belt employs a very thin continuous sheet of solid stainless steel to carry the strands, and cooling water under the belt provides the majority of the cooling by transferring heat through the thin layer of metal. Fans placed over the conveyor bring the temperature down an additional few degrees.

Suitable for high-temperature polymers that cannot be water cooled due to their moisture absorption

“This is an important advancement for our line of cooling conveyors and represents a unique solution for materials, including high-temperature polymers that can’t be water cooled due to their moisture absorption,” explains John Sly, Reduction Engineering’s sales manager.

The cooling conveyors are available as custom-built units to meet the special requirements of laboratory and specialty compounders. The cooling conveyor is commercially available and is already used in a range of applications including metal-reinforced materials, bio-based grades, and medical materials.
