The Flat Disc Refiner is a refiner of single-disc cantilever design with hydraulic positioning of the rotor disc and the front cover supporting the non-rotating stator disc.
The segments are mounted on segment holders for both the rotor and stator. The disc clearance is kept constant during various operating conditions and loads by means of a hydraulic control system. The disc clearance is measured by a TDC (True Disc Clearance).
