Double Disc Refiners

Equipped with a floating rotor, plate change support arm, Timken & SKF shaft support bearings, and optional control system.

Conical Refiners

The latest in shallow angle conical refining. Low no-load HP and no plate clashing.


Like the DD and Conical refiners, Spinnaker-Parason Deflakers incorporate standard bearings & connections.

Screen Baskets

Available with holes, counter-sunk holes, and wedge-wire. Produced on precision CNC machining centers.


Low Intensity Refiner Plates

Zero-draft, reverse-draft, cast, and milled low intensity refiner plates for all refiners.

Conical Refiner Tackle

Spinnaker-Parason conical tackles for all JC and ConFlo refiners. An excellent alternative to the high cost of traditional suppliers.
