Confiner

A conical refiner is a key piece of equipment in papermaking that uses a rotating conical rotor against a stationary conical stator with metal bars (fillings) to mechanically treat pulp, improving fiber bonding, strength, and flow (freeness) for better paper quality and runnability. Pulp enters between the cones, gets forced through the narrow gap by intense friction, and exits refined, resulting in better fiber development and paper properties.
