The refiner plate is the "heart" for refiner machine, using the mechanical action of refiner plate teeth to treat fibers in pulp, to loosen, moderately cut, and separate them into fibers; More importantly, the pulp fibers can absorb the water and then swell during refining , so that lead to the fiber have high elasticity and deformability to meet the requirement of paper production and make the paper have good quality.
According to the application, the refiner plate can be divided into high consistency refiner plate, double disc refiner plate, conical refiner plate, thermal dispersion refiner plate.
According to the plate type , it mainly have four series: cut fin plate, broom fin plate, soft fin plate, and ease fin plate.
The design of the grinding disc must select the appropriate tooth profile to achieve the predetermined beating parameters, and must also have good wear resistance and impact toughness. Considering wear resistance and economy, multi-element alloy grinding discs and high chromium cast iron grinding discs dominate due to their excellent wear resistance. Multi element alloy grinding discs with coarse surface particles tend to have better fiber separation and broom effect; Special steel grinding discs tend to have a more intense cutting effect on fibers.
| Cut fin plate | Suitable for free state pulping, rapidly reducing the wet weight of long fibers under low power consumption, which is beneficial for improving uniformity. |
| Broom fin plate | Suitable for short fiber pulp, with weak cutting effect, maintaining fiber length, and reducing wet weight loss. |
| Soft fin plate | Suitable for multiple types of pulp, with strong drainage and pumping capabilities, reducing power consumption, and improving yield. |
| Ease fin plate | Suitable for slightly viscous pulping, it has a strong effect on fiber separation and pulverization, which is beneficial for improving the degree of pulping |
