There are 2 types mud recycling unit produced by GN, the economic HDD mud recycling system are largely used in HDD mud cleaning and recycling without mud storage and mixing function, an extra storage tank and a mixing unit are needed. The self contained mud recycling system integrated with the function of mud recycling, mud storage and mud mixing, it can meet the large drilling rigs mud recycling requirement. We can produce different treating capacity mud recycling system, such as 200gpm, 400gpm, 600gpm, 1000 gpm and customized treating capacity mud system. They can be used for trenchless HDD project, CBM drilling, geothermal drilling, tunnel boring machine or bored pile project, water well drilling and diamond core drilling.


GNMS-200C HDD mud recycling unit is a 200gpm treating capacity mud recycling system, including double deck mud cleaner with hydrocyclones, feeding pump, mixing pump, mixing hopper, mud agitator and mud gun, the mud tank can be shipped by standard contaianer,
GNMS-400C HDD mud recycling system is a 400gpm capacity mud system, the total storage capacity is 8.5m3, the container shipping dimension is 6000mm x 2220mm x 2158mm. The mud cleaner is a double deck bottom shaker with 8ea of 4 inch desilter cone, with feeding pump and mixing pump.
Except for HDD mud recycling unit, we also produce TBM slurry separation plant, the features of TBM slurry separation plant including:
1. Complete package for Turnkey solution
2. Modular, pre-assembled and small footprint unit for easy and fast installation
3. 5 phase separation system to separate fine solids

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.
