Major components of the centrifuge (As per fig) consist of the rotating assembly, control cabinet,bowl and conveyor drive motors, control system, purge system, vibration switch, and case, base assembly, and skid. The following paragraphs describe these components.

Rotating Assembly For Centrifuge

The rotating assembly consists of a cylindrically shaped, high-strength carbon steel bowl,conveyor assembly, gearbox, and related components. The bowl consists of a straight steel cylinder with a conical section at the solid discharge end and a flat liquid bowl head at the opposite end. Openings are provided at both ends to permit liquid and solid discharges. The bowl ends are supported by roller bearings having grease fittings to facilitate periodic lubrication

Bowl Assembly For Centrifuge

The liquid bowl head at the liquid discharge end contains movable weir plates that permit manual adjustment of the liquid level remaining in the bowl during rotation. Notched locking plates adjacent to the weir plates facilitate precise adjustment. The liquid level or pond depth, along with other factors, helps determine the liquid content of the discharged solids. The conical bowl at the solid discharge end forms an upward sloping beach, where solids collect and are continuously discharged through the solid discharge ports. Replaceable inserts line the solid discharge ports to minimize the rate of wear due to abrasive action.

Conveyor For Centrifuge

The conveyor assembly is a hollow, cylindrical auger that receives the inlet slurry into its interior,disperses it through feed nozzles to the bowl assembly, and transports the solids to the solids discharge outlet. Rotated by an electric motor through a three-stage planetary gearbox, the conveyor turns in the same direction as the bowl but at a higher rate of speed. The outer housing of the gearbox is secured to the bowl, while the shaft is directly connected to the conveyor

Decanter Centrifuge Breif Introduction

Decanter Centrifuge for separation of detrital material of drilling muds is widely used in solid control system for drilling mud to separate the solids phase of mud, remove harmful fine drill solids such as debris, etc. in the mud fluid, or recover weighting materials such as barite etc. so as to reduce the cost of mud fluid.

Decanter centrifuge provides two drive modes: rated frequency drive and variable frequency drive. As to rated frequency drive centrifuge, the rotating bowl speed is fixed, so the speed can be changed only by changing drive pulley; while variable frequency drive centrifuge can achieve large-range stepless speed regulation easily with parameters displayed, e.g. speed and working current.

Centrifuge sales and rent

Centrifuge is a core and expensive equipment for mud cleaning equipment. Some clients will buy and some rent depending on different working conditions. GN Solids Control sales decanter centrifuge for several models to meet clients requirement. GN has sales for decanter centrifuge to over 40 countries like Brazil, Australia, USA, Ecuador, Russia…… Some clients also asked us if we could rent centrifuge to them. The answer is we didn’t rent centrifuge yeat but we are starting to consider this business. As we are setting offices all over the world and keeping stocks and equipments all over the world and rent business will be one of our division soon.

GN decanter centrifuge high speed model is a popular one and sales popular to all over the world. It can separate solids particals above 2-5 microns with 176Gallons per minute speed. GN has designed a new model to keep a large treating capacity to meet more clients application
