DDR refiner segments,Cone refiner disc, round refiner disc, heat refiner disc, dispersing machine refiner disc, hot dispersing refiner disc, etc;
The DDR refiner segments 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 a beating.
The refining chamber consists of two fixed refiner discs fixed on the casing and moving base and two rotating refiner discs installed on the rotating disc, forming two grinding areas. By exchanging refiner discs with different tooth shapes, it can meet the beating requirements of various pulps.
The refiner plate is designed with an appropriate tooth profile to achieve the established beating parameters and has good wear resistance and impact toughness.
