Conical Type Refiner Plate for Pulping

What is Conical Refiner Plate? What is its Operating Process?

The conical refiner plate is the core component for conical refiner. The truncated conical rotor (with rack) and the same shaped stator form the grinding zone, and the clearance between the refiner plate is controlled by an axial displacement adjustment mechanism. The fiber material enters the grinding zone through the feeding channel and completes fiber separation and broom formation under the action of rotational shear. The processed pulp is output through the discharge channel.

Application of Conical Refiner Plate

Newsprint beating system:  achieves stable tapping degree at 38 ± 2 ° SR by optimizing gap parameters.

Adaptability of bagasse pulp: has been validated through industrial testing for its effectiveness in treating non wood fibers, resulting in a 12% increase in pulp yield.

Comparison with Disc Refiner Plate

Single disc structure and double disc structure refiner plate offer stable grinding slurry quality but consume more energy. Conical refiner plate can play a role in certain scenarios where there are special requirements for the contact angle and grinding range of the refiner plate.

In addition, The double cone structure reduces no-load power consumption by 30% compared to the single disc structure, and the three cone device has more advantages in axial force balance.
