Mining project may generate some waste water / waste mud which need to be treated before discharge. GN Solids Control mud treatment system can also apply in this field. Recently we have a similar project for Philippines. It is dual centrifuge system for Mining project

The Dual centrifuge system configuration as below:

1) One set shale shaker to remove the coarse solids particles, separation points above 100microns to 200microns.

The shale shaker GNZS594E-HB is GN 4 panel shaker, which is replacement shaker as Swaco Mongoose. Similar design with composite material shaker screen can reach high treatment performance. For more info of GN Shale shaker, pls check from GN shale shaker website.

2) Two sets high speed centrifuges to remove the fine solids particles, separation points above 2-5 microns.

The centrifuge, GNLW363CG-VFD is GN high speed & variable speed & high configuration decanter centrifuge, which competing with US/European centrifuge brands. Centrifuge applications including

a. High performance water based mud treatment for oil drilling rig solids control

b. High performance oil based mud treatment for oil drilling rig solids control

c. High performance waste water treatment for oil drilling rig drilling waste management

d. High performance barite recovery / mud weight cutting for oil drilling rig solids control

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.

screw conveyor

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.

Hereunder, we want to introduce a kind of equipment connected solid control system and waste management system. It is screw conveyor, or name it auger. It is utilized to transfer solid waste or slurry from solids control system (including shale shaker, mud cleaner or centrifuge) to drilling waste systems for further treatment.
