    Sack Kraft Paper Production Project

    Leizhan is the supplier of the “turnkey” paper plant for production of Sack kraft paper board. The whole sack kraft/testliner board making line contains stock preparation project and paper making machine. Following is the customized paper pulp production solution use waste paper as raw material.


    80T/18H LOCC Stock Preparation Project

    1. Raw material conveying

    BFW1200 Chain conveyor: Mainly used for conveying various kinds of pulp board, waste paper in bulk and in bundlewhich can be horizontal conveyor or inclined conveyor(<30°).

    2. Pulping

    ZDSD25  D Type hypdrapulper: D type structure changes slurry flow ways, make contact between pulp and rotor more quick and frequent.

    3. Cleaning

    ZSC5 high density cleaner: Mainly applied to remove all kinds of heavy impurities in paper pulp, like steples, stones, glasses, etc.

    ZSC6 mid density cleaner

    KH600 low density cleaner: Mainly used for removing heavy impurities in the pulp like gravel, scrap iron, dust and large ink particles.

    4. Screening

    ZNS0.6 mid consistency pressure screen: Mainly used for coarse and fine screening of various waste paper pulp.

    PZ2 reject separator: Used for fiber relief and impurities separate for tailing in the coarse screen system for waste paper pulp.

    FJS0.9 fiber classifier: Mainly used for secondary breaking and screening of waste paper pulp, meanwhile, separating the light and heavy impurities from the pulp.

    5. Pulp refining

    ZDP380 double disc refiner: Used for beating and improve the beating degree of pulp to satisfy the papermaking demand.

    6. Fine screening

    NLS0.6 inflow pressure screen before sack kraft paper machine: Small moter power, high production capacity, energy saving.
