The pulp beating disc refiner plate is the "heart" of the disc refiner and the cone refiner. In addition to the need for excellent wear resistance and impact toughness, the rationality of the tooth profile will directly affect the beating performance. "Three points for paper making, seven points for beating", to process different slurries, different indexes and the number of refiners in series should choose different tooth types. Therefore, the study of the relationship between the theory of specific blade edge load, the theory of specific surface load, rheological effect and beating performance, and the non-isolated understanding of the relationship between the various elements, is important to ensure the fiber bonding strength, filter performance, retention rate, quality of the finished paper and It is very important to save power consumption for beating.
Working Principle of Disc 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.
