High Consistency Refiner(Thermal Shredder), Yunda Innovation design of the thermal shredder have a number of patents,which has superior performance, safety and reliability and wide range of raw materials. The main structure is composed of three parts: Thermal Shredder, Ribbon Feeder and Side feed Screw.

High Consistency Refiner Work Site

Raw materials such as wood chips, bamboo chips are going into the Host Pulping Zone through the high-speed rotating ribbon feeder, and after pulping chips enter the fiber coarse refining zone and fiber hair-like shreds zone. And it shredded into uniform hair-like shreds under the action of the rotary and stationary discs, where the chemicals are added at the same time. Compared to the chips, the hair-like shreds has a larger specific surface and higher chemical reaction efficiency, which reduce chemical consumption and pollution.

Advantage

  • Compared to traditional high consistency refiners, Yunda Innovative Thermal Shredder has multi- advantage: 
  • The clearance between refiner plates is accurately adjusted through electronic and hydraulic control, which is up to 0.01mm; 
  • The Thermal Shredder is equipped with shock sensors and vibration sensors to ensure safe and stable operation of the equipment; 
  • Dynamic balancing comes with G2.5 level accuracy, which ensure smooth operation and lower noise; 
  • Adopting a patented rubber damping limit device to ensure stability of operation process; 
  • Replacing the refiner plates does not require dismounting the pipeline, and it equipped with a refiner plates holder and specialized tooling, which shortens the time for replacing the refiner plates, reduces downtime and improves start-up efficiency. 

Yunda Thermal Shredder is energy-saving, high efficiency, stable and reliable, comparable to international first-class brands; It is a key equipment for i-CTMP.
