Product Description
The pulp refiner is the core component of the refiner in the pulping section of the paper industry, and it is a vulnerable part. Its service life directly affects the quality of pulp, paper quality and production efficiency.
Working principle:
"three-point paper making, seven-point beating", beating is to treat the fibers in the pulp by the mechanical action method of the grinding disc tooth pattern, so that it can be decomposed, appropriately cut and split; more importantly, the fibers absorb water during beating. Swelling makes it have higher elasticity and plasticity and meets the requirements of paper machine production, so that the produced paper can reach the expected quality index.
Grinding disc design has always followed the theory of specific blade edge load (SEL). The research and practice cases of my country's Nantong Huayan Grinding Disc Research Center and Austrian Andritz have shown that specific surface load and rheological effects should be fully considered. The theory of specific blade edge load describes and characterizes the beating characteristics based on the effective load of the impact-shearing flocculated fiber per unit length at the intersection of the rotary blade tooth and the fixed blade tooth edge of the refiner. Specifically, it is determined by the effective power (net power) N of the refiner, the rotation speed n, and the cutting length L per revolution of the grinding plate.
Advantage:
1.Wide range of metallurgies developed for industry needs.
2.It can be designed according to various of versions and requirements.
3.Custom designed plates are developed in shortest time.
4.Stronger plates for longer life.
Four series of multi-element alloy grinding disc plate |
HY Cut fin |
It is suitable for partial free beating, and can quickly reduce the wet weight of long fibers under low power consumption, which is beneficial to improve the uniformity. |
HY Soft fin |
It is suitable for short fiber pulp, with weak cutting effect, maintaining fiber length and reducing wet weight loss. |
HY Ease fin |
It is suitable for multiple types of slurry, with strong dispersing and pumping capabilities, reducing power consumption and improving the output rate. |
HY Broom fin |
It is suitable for viscous beating and has a strong effect on fiber splitting and brooming, which is beneficial to the improvement of beating degree. |
