Drilling cuttings auger manufacturer

As a manufacturer of drilling cuttings auger in China, GN Solids Control produce different size screw conveyor with different length as drilling cuttings transfer equipment. GN screw conveyor is consist of drive end ( including electric motor, gearbox, coupling, frame, etc.), material discharge section ( including screw blade shaft, drive end assembly, etc.), middle section (screw blade shaft, hanging bearing, etc.), feeding section ( including screw blade shaft, feeding port, tailing end assembly) 4 part.


We have screw conveyor of 10 inch diameter, 12 inch diameter, 14 inch diameter, 16 inch diameter, 18 inch diameter, with screw length 12 ft per sections, we have 1 section 12ft, 2 sections 24 ft, 3 sections 36 ft, 4 sections 48ft for client’s different requirement. For the screw conveyor cover, we have option of steel plate cover and grating cover with highest safety standard to prevent objects for falling into the conveyor system to protect users.
Spiral conveyor is a continuous conveying equipment without flexible traction, which uses rotating screws to move the conveyed material along a fixed casing for conveying work.


The advantages of GN Screw conveyor are: simple structure and convenient maintenance; The overall dimensions of the cross-section are not big; It is possible to enter and exit materials at any position in the length direction; It is possible to achieve good sealing effect by tightly closing the cover of the casing. Therefore, screw conveyor are widely used in various industries such as food, medicine, chemical, papermaking, environmental protection, metallurgy, building materials, petroleum, power, etc., to transport various powder, granular, and small materials, such as coal ash, cement, sand, lump coal, grains, etc. There are many types of screw conveyors that can meet the conveying requirements of different working conditions and materials.
If you need a screw conveyor, pls contact with GN sales engineer to select a proper model.

Mini Vacuum Cleaner Pump for Oilfield to International Drilling Company

5 sets of mini vacuum cleaner pump are ready for shipment to international drilling company. The model is GNSP-10B, this is the most popular model mini vacuum cleaner for industrial waste and oil spills cleaning. The vacuum cleaner is 100% air operated to produce high vacuum for suction and discharge the waste sludge, the suction and discharge time can be set by the operator as per many times testing, the suction and discharge distance can be reached by using different suction and discharge hose. The user can select different type hose according to the transferred materials.


The wide range application allow the mini vacuum cleaner to be used to transfer the materials with high solids content, and used to transfer powder materials. It can be worked automatically by the operation panel and suction time & discharge time is set in advance.
For standard mini vacuum cleaner pump, 3 type suction device is included, moveable wheels design for easy movement.
Except for the mini vacuum cleaner, we also have bigger model with higher flow rate.


GNSP-20B vacuum pump is also a mobile type vacuum pump, with max capacity 20m3/h, the max suction distance is up to 500m, it can be used to transfer fluids with max 80% solids content, and max solids size up to 50mm. It can be also worked as vacuum cleaner to pick up oil spills.
GNSP-40B vacuum pump is a fixed type vacuum pump , with max capacity 40m3/h, the max suction distance is up to 1000m, it can be used to transfer fluids with max 80% solids content and max solids size up to 75mm. It can be used to transfer oil sludge, drilling cuttings, powder solids, sand, silt, industrial waste water, animal waste, dredging slurry, and other solids waste.
If you need a vacuum cleaner, pls contact with GN solids control.

Desander and Centrifuge Unit for Construction Mud Treatment to Overseas Company

Recently, One unit of desander unit and decanter centrifuge unit are ready for shipment for construction mud treatment to overseas company. The technical configuration is as below:


The desander unit model is GNMS-1000D, it includes a double deck shale shaker with desander cones, centrifugal pumps, mud tank, tank accessories. It is an ideal compact design desander unit for bored pilings, TBM, HDD trenchless engineering and other construction works, the treating capacity is 1000gpm. After treatment, the clean mud will flow back to drilling machine for reuse or it can be used to prepare for new drilling fluids with mixing hopper and mixing pump. You can use GN produced jet mud mixer unit ( mixing hopper, mixing pump, pipelines, electric control panel on one skid as a complete mixing unit to contact with client’s own storage tank.The separation cut point is 40 microns. If you need to separate fine solids, the desander unit will be re-designed with desilter hydrocyclones, with separation cut point 20 microns. After treated by desilter cone, the clean fluids can be reused for construction, the purpose is to reduce water consumption, reduce construction waste, to meet environmental protection regulation of local government. After long time operation, more and more fine solids smaller than 20 microns accumulated in the mud, which can not be reused, then we will need to use decanter centrifuge unit, which with separation cut point 5 microns. And after the project is finished, it is required to separate the water from solids for final disposal, water will be disposal to river, and the solids for landfill or other construction works.


The decanter centrifuge unit model is GNLW224FT-VFD, the max G force is up to 3077G, and max speed is up to 5000rpm. Working with chemical dosing unit, the construction water will be clean for disposal.

HDD Mud Recycling System to Middle East

Recently one set of 1500gpm HDD mud recycling system are ready for shipment to Middle East, It is checked qualified by third party inspection, it is under packaging for delivery. The technical configuration is as below:

Part 1: mud cleaning system including 1 unit of GNZS594J linear motion shale shaker, 1 unit of GNZJ594-3S16N linear motion mud cleaner, 2 units of centrifugal pump as feeding pump of desander cone and desilter cone, mud agitator, lighting system and mud tank with tank accessories and electric control system

3 pcs of 10 inch desander cone and 16pcs of 4 inch desilter cones are installed on a GNZS594J shale shaker, the bottom flow shaker is same model with primary shale shaker, when it is under maintenance, which can be used as back up. 4pcs of composite material frame shaker screens are installed on the shale shaker, with total screen area 2.73m2, the deck angle adjustment range is from -1º to +5º, the max G force is up to 7.5G, it is adjustable for different requirement.

Part 2: mud mixing system including 1 unit of mud tank, with mud agitator, mixing pump, mixing hopper , lighting system, explosion proof control system

Part 3: spare shaker screens to be installed on the shale shaker and mud cleaner, tools

The whole system is connected by pipelines for smooth working, the HDD slurry can be picked up by submersible slurry pump from mud pit to the mud cleaning system, the treated fluids flow to mud mixing system to prepare for new drilling fluids, which can be reused for drilling machine. A good mud recycling system can protect the drilling machine and extend its working life, and also reduce drilling waste accordingly. If you need a customized HDD mud recycling solution, pls contact with GN Solids control.
