4. Separation cut point: 2~5 Microns
5. Driving method：Diesel + Hydraulic drive
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.
