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.
tunsten alloy tile for screw protection
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
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.

Many customer wondering the difference of the 2 kinds of dryr and do not know how to choose the suitable one.
High G shale shaker (H-G) VS Vertical G cuttings dryer (V-G)
GNZS594 High G shaker dryer
1) Price of Vertical G cuttings dryer (V-G) is much more higher than High G shale shaker (H-G)
2) Their application field is different. High G shale shaker (H-G) is mainly used to treat water based mud drilling cuttings. While Vertical G cuttings dryer (V-G) mainly used to treat oil based mud drilling cuttings
3) High G shale shaker (H-G) can be used to separate oil based mud drilling cuttings, while Vertical G cuttings dryer (V-G) cannot used to treat water based mud drilling cuttings
Vertical G Cuttings Dryer
Difference of High G shale shaker (H-G) & Vertical G cuttings dryer (V-G) for oil based mud (OBM)
Both High G shale shaker (H-G) & Vertical G cuttings dryer (V-G) can be used for oil based mud, but there is difference on performance.
High G shale shaker (H-G) can reduce the oil on cuttings (OOC) to 15~20% after treatment. For many customer, it is not dry enough. Other treatment process is necessary. But the Vertical G cuttings dryer (V-G) can reduce the oil on cuttings (OOC) to 3~5%. The discharge from Vertical G cuttings dryer (V-G) can take away directly for road construction or other function. Or Feed to Thermal Desorption Unit for further treatment.

There are rubber ring for sealing on most shaker screen model, like Derrick503 screen, Derrick48-30 shaker screen, Brandt Cobra shaker screen, GN Solids shaker screen, and many other shaker screen models.
Functions of the sealing rubber:
1) Sealing between screens and shaker deck. To avoid un-treated dirty mud seep into mud system, and damage the mud system machine.
shaker screen sealing rubber
2) To reduce the bad effect of vibrating to the shaker screen. Protect screen from strong vibrating.
What will happen if the sealing rubber not workable
1) The screen frame will touch directly with shaker deck, and damaged within a very short time
2) The worst result is, if the screen rubber damaged, the dirty mud from well head will flow into mud system directly with much solids. It requires a higher capacity on downstream equipment processing, or even make damage to the downstream machine, like desander, desilter or vacuum degasser
If the material of the sealing rubber not strong enough and not very good at anti-corrosive, the high temperature drilling mud with heavy sand will damage the rubber very soon. The shaker screen will be broken very soon. Dirty mud flow into the mud system from the shale shaker deck with heavy sand and solids. It will have bad effect to the mud system.
GN Solids Control utilzie high quality material for sealing rubber. They can offer high quality shaker screen with reasonable price.
GN Solids Control has already developed the 20 foot containerized dewatering unit for drilling mud recovery, as without the chemically enhanced technology, operators would be left with the accumulation of colloidal and ultra-fine drilled solids in the drilling mud circulating system. Ultimately leading to excessive mud densities, pipe torque/drag, mud loss, disposal fees, and overall well cost.
GN 20 foot Containerized Dewatering Unit
GN 20 foot containerized dewatering unit including all the components for adding chemicals, dewatering polymers,and mixing systems. The dewatering unit control system is organized by the PLC system to allow automatically operation. The customter mostly use the dewatering unit for water based mud.The result is a polymer-enhanced flocculation of colloidal and ultra-fine drilled solids that can be efficiently removed by a GN high Speed decanter centrifuge.
The customer can choose to have the decanter centrifuge on a separate skid or included in the dewatering unit container, in such case the container should be 40 foot size to have enough space for setting up the centrifuges and the feeding pumps.
Dewatering Unit
Some case studies for the drilling mud dewatering unit
The Dewatering unit application at the well allowed reduction of the liquid-waste volume by 32% for the first two sections and by 27% for the entire well. Around 350 m3 of water was returned to the system for fresh drilling fluid mixing thus reducing the cost of water delivery. All drilling fluid left after the last section was also processed through the Dewatering unit and the returned water was used for completion operations. Although application of the Dewatering unit added additional upfront cost to the well construction, the waste-volume reduction allowed a 20% waste disposal saving as compared to offset wells.
