GNLW363CG is a Dual Motor Decanter Centrifuge. It is the latest design high speed centrifuge designed and made by world leading manufacturer: GN Solids Control. The centrifuge is widely used in worldwide drilling rig job site.
GNLW363 is a 14 inch decanter centrifuge. GN offers 2 standard 14 inch centrifuge for customers’ option. High standard GNLW363CG is made from top ranking materials, to compete with U.S and European brand. Economic standard GNLW363CD decanter centrifuge is with the same design with high standard. The difference is that, some parts is chose from economic standard, but the material standard is still higher than normal Chinese brand.

Feb. is the New year month for all Chinese people. But it is one of the most busy month for GN. Besides 5 tank systems and other equipment, GN Solids Control dispatched 19 sets decanter centrifuge in this month.
1) 16 GNLW363CG dual Motor Decanter Centrifuge together with 20 pumps for an Africa customer.
It is only the first batch of the shipment. Another half (16 centrifuges and 20 pumps) will be dispatched weeks later.
The customer order the same model GNLW363CG centrifuge, with fixed speed control. GN offer different size of pulley and belt for different fixed speed. So customer only need to change pulley and belt, customer can get lower speed, high speed and middle speed for the same one centrifuge.
The 32 sets centrifuge will be used for barite recovery with lower speed, and for fine solids recovery with high speed.

2) 1 set GNLW363CG dual Motor Decanter Centrifuge together with 1 set vertical cuttings dryer dispatched for Africa mud service company.
They will be used for drilling waste management. With its patent design, GN vertical cuttings dryer GNCD930C can be used to treat both water base mud and water base mud. Even U.S and European dryers, they cannot treat water base mud.

3) 2 sets GNLW363CG dual Motor Decanter Centrifuge together screw conveyer and dewatering unit dispatched for a Middle east drilling company. The end user is a National drilling company. They saw our equipment running for their rigs, so appointed to buy from GN for their new projects.

Furthermore, totally another 27 sets GNLW363CG dual Motor Decanter Centrifuge will be dispatched for overseas customers in March.

GN new year holiday will start from 13th Feb. ~ 26th Feb.. The office and warehouse will be closed during that time. For urgent, you can contact GN Solids America and purchase from GN Solids America directly. We have storage in Houston for normal solids control and drilling waste management equipment, and some normal spare parts, like hydrocyclones, shaker screens.

GN Solids America is the 1rst China solids control brand having warehouse and base in Houston, USA. GN offers sales service and rental services in U.S.A market with solids control and drilling waste management equipment. Below is part of equipment now in stock in GN Houston warehouse:

Furthermore, GN will show its advanced design solids control and drilling waste management equipment is Beijing CIPPE oil show in March. Welcome you come and visit.

GN Solids Control is a specialized manufacturer for the drilling mud solids control and drilling waste cuttings equipment. The shale shaker is one of GN’s main products. For this main product, at this time all the model GN’s provided is the linear motion vibration mode. As per the requirement coming from different industry and the customer’s preference, GN’s shale shaker is classified by the treating capacity and application.

GN’s shale shaker is classified as 200GPM, 500GPM and 600GPM. The smallest model is always be used in the compact system for the job site with limited location area. GN’s 600GPM model could be used in both the common solids control and waste management system. When talking about the slurry feeding type of GN high G force drying shaker, there are 3 types used for different application. The 3 types of the feeder box are the top located design; back located design and hopper designed. For the top located design feeder box, the shale shaker is often proposed to use in the mud recycling system for the HDD projects. As the mud tank in HDD are always narrow, so there is no enough space of the tank surface to locate the shale shaker. In HDD project, the drilling mud are always fed to the shale shaker through the pump, the drilling mud come to the screen with very low pressure, so the drilling mud would come to the screen directly from the top located feeder box. While in the oil drilling projects, the drilling mud always comes out from the drilling hole with high pressure. Thus there will be a buffer box to reduce the high pressure of the drilling mud, the feeder box is designed like an “n”, and the drilling fluids need overflow into the shaker deck.

For the hopper design feeder box, it is specially used for drilling waste cuttings dryer system. As the waste cuttings are always very thick, and the fluidity is not as good as the drilling fluids. When delivered to the drying shaker by the screw conveyor, the waste cuttings have to get into the shaker via a large opening feeder box. For this type hopper, it is easy to let the cuttings get in and performance would be very well.

Screw conveyer also called auger. It is widely used in building industry, chemical industry, environmental protection, medicine, metallurgy, food industry, and so on. U-trough shaft screw conveyer is the most common model been used to transfer drilling cuttings in drilling waste management field. It can be feed or discharged at different section or port, very flexible in use. U-shaped conveyor trough is closed, and the cover can be opened. The cover material can be steel plate or good sealing, or Galvanized steel grating plate for easy observation. Depends on the diameter of the auger impeller, there are 12inch screw conveyer, 14 inch screw conveyer, 16 inch screw conveyer and 18 inch screw conveyer.

Below table is parameters for common model screw conveyer

Suitable maintenance can extend lifetime of screw conveyer and insure a reliable performance.
Recommend maintenance of screw conveyer for drilling cuttings transfer is as below:
1) Check the gearbox, bearings and other rotating parts, and add lubricating oil periodically
2) Check the screw conveyer impeller periodically, if there is serious wearing, repair and re-weld it  
3) Do not use the screw conveyer with overload.
4) If there is abnormal noisy during running, stop the screw conveyer immediately and check the reason.

Applications of drilling cuttings transfer screw conveyer
1) It can be used in level to collect drilling cuttings discharged from solids control mud system, like solids control shale shaker, desander, desilter, mud cleaner. And then another set screw conveyer used to transfer the cuttings to next process equipment.
2) Feeding for vertical cuttings dryer, and then transfer the solid waste discharged from vertical cuttings dryer

3) Transfer drilling cuttings or materials from one place to another
