Disc Refiner is the main equipment for producing mechanical pulp and chemical mechanical pulp. The main types are: Single Disc Refiner, Double Disc Refiner and Conical Refiner. Double Disc Refiner is very popular among those.

Structure Feature of Double Disc Refiner

The two sides of the moving disc are provided with two tooth surfaces, which form two grinding chambers with two fixed plates. Even if the speed is high, there is no moving disc deflection problem. The steam produced by the refinering  process can be discharged by two feed ports and one discharge port. The disc refiner of this construction does not require large thrust bearings.

Advantages of Double Disc Refiner

Increasing the speed will make the disc refiner produce great centrifugal force, affect the normal distribution of the slurry between the discs, and cause the stability of the equipment. Without increasing the rotating speed and increasing the disc diameter, the refining area of double refiner increased by two times, and the yield and the quality of pulp improved.
