    CCD DECANTER CENTRIFUGE IS SPECIAL DESIGNED FOR CIVIL CONSTRUCTIONS MUD TREATMENT. CCD Series Decanter Centrifuge can be applied to horizontal directional drilling, water well drilling, micro-tunneling, large diameter tunneling, hydro excavation mud processing, slurry wall/foundation drilling, TBM Machine, Pipe jacking project etc. The applications including but not limited to:

    HDD mud system, Water well drilling system for ultra-fine solids removal

    Mining tailings separation and recovery

    Micro-tunneling and large diameter tunneling bore machine (TBM) slurry mud treatment

    Hydro excavation mud recycling system, to cut mud weight through remove fine solids

    Mud treatment in Foundations/walls construction

    Desanding / desiltering in pipe jacking construction

    River channels sludge dredging / dredging mud recycling system of river channels

     

    By cooperation with coarse screen shaker & fine screen shaker, decanter centrifuge is necessary for big borehole construction to separate the fine silt and clay particles down to 3~5microns in large processing capacity. Normally, the large capacity of slurry from excavation process can be treated by scalping screen shaker, fine screen shaker with cyclones and high speed decanter centrifuge.

     1) The slurry will flow to slurry holding tank with agitator & slurry pit pump
     2) Pit pump suction the slurry mud and transfer to scalping screen shaker with coarse screen to remove the coarse solids & sticky clays, cut point 100~500microns
     3) After Scalping screen shaker, the coarse solids will be discharged outside desanding plant; the slurry with fine solids will be drop down to tank sump 1
     4) Centrifugal pump with open impeller will suction the slurry mud and feeding to cyclones in proper feeding pressure, cut point 20~100micronszAfter fine screen shaker with cyclones, the overflow will report to tank sump 2; zeventually overflows to the sump 3 of the tank.

     

    Positive Displacement pump will transfer the slurry mud from the 3rd chamber of tank to big bowl big capacity decanter centrifuge where the ultra-fine solids will be separated out by centrifugal G Force. The clean slurry will be pumped back to the excavation process.
    The modular slurry plant with scalping screen shaker & cyclones is widely used in civil engineering construction. We have standard desanding plant for fast delivery time. Also, we can customize per details request from customer
