Paper Mill Equipment Double Disc Refiner
The double disc refiner is installed in the stock preparation line to improve beating degree and optimize fiber properties for paper making. This double disc refiner processes various raw materials – wood pulp, chemi‑mechanical pulp, chemical pulp, and waste paper pulp – by using interchangeable refiner plates with different tooth patterns. By controlling the refining intensity, the double disc refiner enhances fiber bonding, increases strength properties, and ensures uniform stock quality. Its double‑disc design provides higher refining efficiency and better plate utilization compared to single‑disc units. Operating at 3‑5% consistency, this double disc refiner prepares the stock to meet the exact paper machine requirements.

Select this double disc refiner for flexible beating control across a wide range of pulps. The Φ380 model suits small to medium mills (6‑20 t/d), while the Φ450 model handles up to 60 t/d with higher power options. Both double disc refiner models are built for easy plate changes and low maintenance. By using a double disc refiner, you improve fiber development, reduce energy consumption per ton, and achieve consistent paper strength.
