The stock preparation project is equipped with a ZDSD23 D-type hydraulic pulper, which features an advanced D-type cylinder structure design, significantly shortening pulping time and increasing production capacity. The pulped material then enters a ZSC3 high density cleaner (pressure drop 200 kPa), effectively removing heavy impurities. The cone of this high density cleaner is made of wear-resistant ceramic material, ensuring a long service life.

In the cleaner stage, the stock preparation project employs a three-stage cleaner system with high, medium, and low concentrations to ensure high purity of the finished pulp, providing high-quality fiber raw materials for subsequent refining and paper making processes. In the refining stage, the ZDP450 double disc refiner precisely controls the beating degree, providing qualified pulp that meets the paper strength requirements for subsequent paper machines. In the approach flow system, the stock preparation project is equipped with an inflow pressure screen, effectively reducing pressure pulses, minimizing pulp flow fluctuations, reducing fiber flocculation, and improving paper web uniformity.
