As one of the solids control decanter centrifuge manufacturer in China, GN solids can provide different explosion proof standard decanter centrifuge with different size for their applications, we have ATEX, IEC EX, CNEX for option, we can produce 9 inch bowl mini centrifuge, 14 inch and 18 inch bowl solids control decanter centrifuge, 22 inch big bowl big volume centrifuge and 30 inch bowl decanter centrifuge. We can also provide 3 phase decanter centrifuge for oil, water, solids separation for oil waste treatment and oil sludge separation system.

Track Mounted Mud Recycling System for Australia Customer

Recently one set of track mounted mud recycling system are ready for delivery to Australia Customer. It is a mobile mud system for mud cleaning and recycling, processing capacity is 400gpm, the separation cut point is 15~20 microns. The features of the track mounted mud system is as below:
1. Compact design, Easy movement, flexible application for geothermal, diamond core drilling and other drilling projects.


2. Cost effective, the system reduce the solids content in the drilling fluids and reuse the drilling fluids for drilling, also the solids disposal cost is reduced.
3. Lower maintenance cost, easy maintenance, lower operation cost, minimum downtime
The technical configuration is as below:


The mud cleaner GNZY754K-Y6N, with double deck shale shaker, the bottom layer shaker screen as coarse solids separation screen, the top layer shaker screen as mud cleaner separation screen, the top layer screen is 1.35m2, the bottom layer screen is 1.35m2. The mechanical deck angle adjustment range is -3° to +5° .The mud cleaner hydrocyclone is 6pcs of 4 inch. The track drive power is 18.5KW, the mud system power is 15KW, including submersible pump 11KW and mixing hopper. The total tank volume is 3200L. The recommend generator power is 48KVA.
The track mounted mud recycling system consists of the track system, hydraulic jacking legs, mud tank with double deck mud cleaner, generator, lightings, etc. The drilling mud after treatment will be transferred to buffer tank, the submersible slurry pump will transfer the recycled mud to drilling machine for reuse. The solids separated from the mud cleaning unit will be recycled and transported.


Except for track mounted mud recycling system, we can also produce track mounted decanter centrifuge package, and track mounted solids removal unit. If you need a diamond core drilling solids removal unit, pls contact with GN solids control.

Double Deck shale shaker and cuttings dryer for Africa drilling company

One set of double deck shale shaker and one set of vertical cuttings dryer are ready for shipment to Africa for drilling cuttings treatment system.
The double deck shale shaker will be applied as high G force drying shaker to separate the coarse solids, it can be used for both water based drilling cuttings and oil based drilling cuttings. The anti splash cover on the top to prevent the drilling mud from splashing. The top layer and bottom layer total 6pcs shaker screens are composite material frame for longer working life and better separation performance.


The vertical cuttings dryer is ideal equipment to be used for oil based drilling cuttings treatment, after treatment, the oil content on the cuttings is below 5%, the fluids will flow to an intermediate tank, then feed the fluids to decanter centrifuge for further treatment, the fine solids will be separated out by decanter centrifuge, the fluids can be reused for drilling. Before treated by decanter centrifuge, the fluids can be treated by drying shaker to reduce solids content, it will increase the decanter centrifuge treating capacity and performance, also it can prevent the centrifuge bowl from damaged by the high solids content.


GN standard drilling waste management system GNCM-40A is consist of VFD decanter centrifuge, vertical cuttings dryer, flushing pump, centrifuge feeding screw pump, fluids collection tank, skid, electric control system, accessories. The compact design with small footprint is loaded into standard container.
Except for drying shaker and vertical cuttings dryer, GN solids control also produce drilling waste treatment decanter centrifuge, including high speed decanter centrifuge, VFD decanter centrifuge, Fully Hydraulic Drive decanter centrifuge, we provide different explosion proof standard for option, IEC EX, ATEX, CNEX. For more information about high G drying shaker and vertical cuttings dryer, pls contact with GN Solids Control.

3 Phase Decanter Centrifuge for oil water separation to China ES Company

One unit of three phase decanter centrifuge is ready for delivery to China Environmental Science company for oil water separation.
The three phase decanter centrifuge working principal is as below:


The solids, oil and water with different gravity, so the generated centrifugal force is different. The solids with largest specific gravity will generate highest centrifugal force, the next is the heavy phase liquid ( water) and the light phase liquid (oil). Due to different centrifugal force, one solid layer and two liquid layer are formed. The solids to be pushed out by the screw, the liquids are separated out from their respective nozzles, the solids oil water separation can be achieved.


GN three phase decanter centrifuge is designed for oil water solids separation under 24 hours continuous working and easy operation & maintenance. The main components including centrifuge driving system, decanter bowl, screw inside the bow, centrifuge skid and VFD control panel.
The 3 phase decanter centrifuge is installed on the mud tank or on the telescopic skid with feeding pump, it has been widely used for oil sludge treatment system. The oil sludge can not be feed into the three phase decanter centrifuge directly, the sludge vacuum pump will pick up the oil sludge from waste pit to the pre-mixing tank, with chemical jetting, heating and agitating, the submersible slurry pump will suck from the pre-mixing tank to shale shaker module to separate the coarse solids and reduce solids content, the fluids discharged from shale shaker will be feed to two phase decanter centrifuge with proper chemicals for fine solids separation. The liquid treated by the 2 phase decanter centrifuge can be feed to three phase decanter centrifuge for oil water separation by adding proper chemicals.
For more information of three phase centrifuge, pls contact with GN solids control.
