Screw conveyor is widely used in drilling mud solids control & waste management as important transportation equipment. Proper use of screw conveyor can make the field job with small footprint and high working efficiency. Let’s draw some conclusions on screw conveyor application in drilling waste management.
1) Connection between mud solids control system & drilling waste management system
The screw conveyor can positioned paralleled with solids control system, equipment like shale shaker, desander, desilter (or mud cleaner, combination of desander & desilter). The paralleled screw conveyor can collect the drilling cuttings discharged from solids control equipment and transport to next slant screw conveyor. This screw conveyor is for feeding for Hi-G dryer or Vertical-G dryer.
2) Feeding for Hi-G dryer & Vertical-G dryer
GN drilling waste management system, the first separation phase is generally equipped with Hi-G dryer or Vertical-G dryer. They both can be used for water based mud, oil based mud & synthetic based mud. Generally, the Hi-G dryer is more proper for water based mud; vertical-G dryer is more proper for synthetic based mud with comprehensive consideration.
The screw conveyor can make the feeding more even/homogeneous, in this case, the working performance of Hi-G dryer or vertical-G dryer can be stable.

3) Discharge transportation from Hi-G dryer & Vertical-G dryer to trucks
After treated by Hi-G Dryer or Vertical-G dryer, the solids discharge generally will be transported to trucks via screw conveyor, and then go to TDU workshop for finalize treatment; the liquid part will go to next separation phase, by high speed decanter centrifuge.
4) Discharge transportation from Decanter Centrifuge to trucks
After treated by Decanter Centrifuge, the solids discharge generally will be transported to trucks via screw conveyor, and then go to TDU workshop for finalize treatment; the liquid part will go to next separation phase, Dewatering unit (Dewatering Centrifuge with FLOCCULENT UNIT ).
