In order to focus on common size centrifuge GNLW363 and big bowl centrifuge GNLW553, shorten the leading time of the 2 most hot sale model, the manufacturing GN Solids Control decided to stop the medium model GNLW454, and good price for sale the storage.

The model has been stopped making. How customer get spare parts and after sales service?

It is absolutely no need worry about spare parts and after sales service. GN can offer spare parts at most 30 days after customer order. After sales service and guarantee exactly the same with other model.

There are many customer have interest on the for sale centrifuge, the chance should belongs to people come first. No hesitate, contact GN now.

GNLW454 is the medium size centrifuge. GN hot sale model is common size GNLW363, it is equivalent to Derrick DE-1000 and Swaco 518. For big bowl, GN can offer GNLW553. You can contact GN group or more information of GN Centrifuge.

 

There are mainly 3 types protection for solids separation centrifuge propeller screw. Many customer do not know the difference of them and wondering about how to choose the suitable one for its centrifuge. Below is the elaborate for the difference of the 3 screw protection design.

1) Tungsten carbide hard surface for screw protection: It is the most common type in China. Nearly all other companies make this type, besides GN Solids Control Co., Ltd. It is easy for process, and cost lower. But the height of the welded Tungsten carbide on the screw surface is very thin, only around 1mm. This type of centrifuge is cheaper, but not good at anti-friction and anti-abrasive. If the solids content high, after half year or 1 year, not more than 2-year time, the Tungsten carbide hard surface will be worn out and the centrifuge will lose balance. The users need to open the centrifuge bowl, welding again to maintenance it and make dynamic balance again. It requests the operator with a higher specialty, and more cost on maintenance.

2) Interchangeable ceramic tiles for screw protection: It is interchangeable small pieces, with exact same weight and dimension. It is strong. And mostly, it has a higher function on anti-abrasive under heavy Acid / Soda corrosion, even better than Tungsten Alloy Tile. Therefore it is mostly used for mining industry. Its cost higher than Tungsten carbide hard surface. The height of the each ceramic tile is reach to 4mm, much more anti-friction than Tungsten carbide hard surface.

Users only need to replace the worn out piece with new one, new need to make dynamic balance. Easy for maintenance.

3) Tungsten Alloy Tile for screw protection: It is the most perfect one and most anti-friction. It is interchangeable small pieces, completely made from each piece with exactly the same weight and dimension. It is the most expensive type, as the material is expensive and a higher request on machining Précising. The height of the each ceramic tile reaches to 4mm, much more anti-friction than Tungsten carbide hard surface, and even strong than ceramic tiles. It is mainly used for barite recovry, fine solids separation and drilling waste managment field.

Users only need to replace the worn out piece with new one, new need to make dynamic balance. Easy for maintenance.

As world famous manufacturer on solids control and waste management centrifuge and vertical cuttings dryer, GN Solids Control offer centrifuges with ceramic tile or tungsten alloy tile. Tungsten carbide hard surface do not recommended. The users can choose ceramic tile or tungsten alloy tile according to its real condition and its budget.

There are different types of centrifuge with different speed for drilling fluids processing. For a more viable application on centrifuges for different kinds of treating of drilling fluids, many customers choose variable frequency drive (VFD) centrifuge decanter.

But always, they are wondering about how to choose the right speed for a certain application for the best performance. Actually, it is G force who effect the performance of separation. We choose the suitable speed for the right G force.

Below, we take example of a GNLW363VFD centrifuge. It is the equivalent model for Swaco 518 and Derrick DE-1000 centrifuge for drilling fluids processing.

Swaco 518 Equivalent Model Decanter Centrifuge

Swaco 518 Equivalent Model Decanter Centrifuge

There mainly 3 functions for drilling fluids processing:

1) Barite recovery: It usually uses middle speed centrifuge. It is the first separate with decanter centrifuge in the drilling fluids purification. Lower G force around 1000 usually required. Per difference of mud, users can adjust speed to change G force in small scope. For GNLW363VFD centrifuge, users can adjust speed around 2200rpm.  

2) High Gravity Solids (HGS) with lower speed: usually, around 1200G. With GNLW363VFD centrifuge, users adjust speed around 2500rpm

3) Low Gravity Solids (LGS) with high speed: G force around 2000G. Like fine solids separation, it needs higher speed.  With GNLW363VFD centrifuge, users adjust speed around 3200rpm

GNLW363VFD centrifuge is the hottest model from China top manufacturer for Solids Control and Drilling Waste management, Unlike Derrick and Swaco centrifuge, GN centrifuge design is also available for mechanical changing of centrifuge speed. For some professional customer with tighter budge, but like top quality, GN Solids Control company will offer 3 different types of pulley for 3 different speeds.

For more information on drilling fluids decanter centrifuge, you can contact with GN Group for solution.   

 

Decanter centrifuge is widely used in drilling site, like oil and gas drilling, coal bed methane (CBM), HDD. GN Solids Control is China leading manufacturer on high quality decanter centrifuge. GN decanter centrifuge model GNLW363 is equal to Derrick DE-1000 and Swaco 518. GN can offer this centrifuge model in stock with very competitive price.

Principle of decanter centrifuge separation

Different solid or particle have different density and flow speed, Drilling Mud decanter centrifuge adopts centrifugal force to separate solids / particles out of drilling fluid. Drilling mud decanter centrifuge also can separate particles with different size and density.

Drilling fluids enter the bowl through the inlet tube. It is accelerated smoothly by an inlet rotor. The generated drilling mud decanter centrifuge forces make the solids collected on the wall of the bowl. The conveyor and the bowl rotate in the same direction, but at different speeds, which caused a differential speed, and enable the solids moving towards the conical end of the bowl for removal.
