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.
