Screw protection of drilling decanter 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.

How to choose the right speed for drilling fluids centrifuge

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.

Drilling mud weighting equipment and system

As one of the few API and ISO certified manufacturer,GN Solids Control design various drilling mud weighting equipment and system for Petroleum drilling,Micro-Tunneling,Horizontal direction Drilling,downhole drilling etc.

To know why people need to weight the drilling mud as operation goes,firstly,we need to know

Composition of drilling mud

Water-based drilling mud most commonly consists of bentonite clay (gel) with additives such as barium sulfate (barite), calcium

Drilling mud weighting system
Drilling mud weighting system

carbonate (chalk) or hematite. Various thickeners are used to influence the viscosity of the fluid, e.g. xanthan gum, guar gum, glycol, carboxymethylcellulose, polyanionic cellulose (PAC), or starch. In turn, deflocculants are used to reduce viscosity of clay-based muds; anionic polyelectrolytes (e.g. acrylates, polyphosphates, lignosulfonates (Lig) or tannic acid derivates such as Quebracho) are frequently used. Red mud was the name for a Quebracho-based mixture, named after the color of the red tannic acid salts; it was commonly used in 1940s to 1950s, then was made obsolete when lignosulfonates became available. Other components are added to provide various specific functional characteristics as listed above.

While operation goes,some material as composed of the drilling mud above may lose.To keep the balance of the drilling mud,drillers need to weight the drilling mud by adding chemicals into the mud.Usually,a complete drilling mud weighting system is consist of following equipment or accessories.
