Stock Preparation Equipment Double Disc Refiner

Double disc refiner consists of two parallel, counter-rotating discs with refiner plates on each side. The pulp enters the refiner through the center and passes through the narrow gap between the discs. As the discs of double disc refiner rotate, the fibers are subjected to intense mechanical forces, resulting in refining.

Application & Features

1. The double disc refiner refines the pulp by mechanical action, breaking down the fibers and reducing their size.

2. It improves the fiber bonding, fiber flexibility, and fiber length distribution, resulting in improved paper properties.

3. Double disc refining helps to increase the pulp consistency and enhance the physical properties of the paper, including strength, smoothness, and printability.

4. It contributes to improved drainage and de-inkability of the pulp.
