3 Sets GNTBM-360 Slurry Separation Plant for Overseas Pipe Jacking Project

Recently 3 sets of GNTBM-360 slurry separation plant are shipping to overseas pipe jacking project.

The technical specification is as below:
The treating capacity is 360m3/h, separation cut point is 30μm, the effective tank volume is 24m3, total power is 164KW, the shipping dimension is L6058×W2438×H3115mm, it can be shipped by bulk cargo vessel, the gross weight is 23000 kgs. The GNTBM-360 Slurry Separation Plant consists of 2pcs of 16 inch desander cone, 8pcs of 6 inches desilter cone, with desander desilter feeding pump 75KW, the desander cleaner is GNZS1536-2A with lower deck screen area 5.4m2, upper deck screen area 5.4m2, the deck angle is±3 °.The mud tank size is same with 20ft container size, the equipments on top of the mud tank with lifting frame for convenient lifting and installation. The walkway and guardrail around the mud tank for convenient operation, the control panel is installed for easy operation for people stand on the ground.


The working process is as below:
The transfer pump feed the slurry to the double deck shale shaker lower deck through the coarse screening inlet pipe, to remove the coarse solids from the slurry. The built in #1 slurry pump transfer the slurry separated by coarse screening to desander cone, the clean mud flow out from the overflow port, the cuttings is discharged from the desander drop in apex, and fall on the upper deck of the double deck shale shaker to recover more useful fluids. The built in #2 slurry pump feed the clean mud to desilter cone, the clean fluids flows out from the desilter upper part, and overflows to the storage tank outside the system, which can be reused for the TBM machine. The solids particles will be dried and collected for disposal.

6. Mud tank volume： 2m3
7. Total power consumption: 40KW
8. Mixing hopper
The treatment process is as below:


The mud is pumped into the sedimentation bin of the buffer tank, so that the large particle sedimentation. After that, the mud overflow to the slurry supply bin of the feeding tank, the pumped by the #1 slurry pump to the hydraulic centrifuge for ultrafine solids separation. If without the sedimentation process, one unit of mini shale shaker will be used to separate the coarse solids from the mud. The mud treated by the hydraulic centrifuge flows into discharge tank and transferred to drilling machine by No.2 transfer pump, the treated clean water can be reused to prepare for new drilling fluids and used by the core drilling for cost saving.
