Development History and Separation Theory of Horizontal Spiral Centrifuge


Horizontal Spiral Centrifuge Development History

Centrifuge is widely used in oil industry from the latest 1980s.  After years of development and application, There are many types of centrifuge, such as Horizontal Spiral sedimentation centrifuge, perforated rotor centrifuge, hydraulic turbine and other types. The Horizontal Spiral Centrifuge is widely used in drilling industry. According to the different speed, Horizontal Spiral Centrifuge is divided into low speed Horizontal Spiral Centrifuge, intermediate speed Horizontal Spiral Centrifuge and high speed Horizontal Spiral Centrifuge.

Horizontal Spiral Centrifuge Structure

Horizontal Spiral Centrifuge is made of the main motor, polling motor power, fluid coupling, drum assembly, differential mechanism and feed liquid pump. Outer structural shape of Horizontal Spiral Centrifuge might be something different beacause of application in different industries.



Horizontal Spiral Centrifuge Separation Theory

The separation process of solid phase and liquid phase is in the drum. High speed rotary of drum drive the drilling fluid high speed rotary, drilling fluid is left to the wall of the drum for a liquid circle, because the solid phase in the liquid circle is suffered the centrifugal force which is hundred and thousand times bigger than its own gravity, it overcomes the resistance of drilling fluid viscosity and rapidly sediment to the inner wall of drum and forming solid phase, liquid form liquid phase. The ratio of the solid phase centrifugal force and it own gravity is called the separation factor of centrifuge.

Horizontal Spiral Centrifuge Pushing Slag

Pushing slag work of Horizontal Spiral Centrifuge is completed by screw propeller, in the function of differential mechanism, screw propeller and the drum form a certain speed difference, then the solid phase particles are precipitation to the drum inner wall are scraped from the wall of the drum, it is pushed to the small end by spiral impeller, in the process of propulsion is dehydration, at last get to disilting nozzle.

Brightway is the Horizontal Spiral Centrifuge manufacturer in China. The products of BW series Horizontal Spiral Centrifuge has been exported to 48 countries in the world. BW series Horizontal Spiral Centrifuge can be used in the many industries, such as oil well drilling, HDD, TBM. if you are interested in Brightway BW series Horizontal Spiral Centrifuge, please click here: http://www.solidscontrolsystem.com/product-item/decanter-centrifuge/

Brightway Dewatering Unit and System Instruction



The 20FT Dewatering Unit provides a process of chemically enhanced configuration to remove the fine solids less than 5 microns from the water based drilling fluids.

As it known that traditional solids control equipment’s like shale shaker, desander, desilter, and decanter centrifuge will removes solids upper than 5 microns, for colloidalsize particles which is less than 5 microns will build up in the drilling mud system.

To maintain the drilling mud properties, the operators have to dilute the drilling fluids with water; this consumes more water and creates more drilling waste.

By utilizing the 20FT dewatering unit, the result is a chemically enhanced flocculation of colloidal and ultra-fine drilled solids that can be efficiently removed with the BWLW365G dewatering centrifuge.

For limited and zero discharged closed loop system, the  dewatering unit is a very important unit to keep the mud clean and reduce the drilling waste which has to be sent for treatment and disposal. Before entering the dewatering phase, for the weighted drilling mud, firstly it enters a barite recovery centrifuge to recovery the barite to the active mud system. The 20 FT containerized dewatering unit can be transported as a standard 20 ft. container. The system includes all the standard dewatering components.

Brightway also have the dewatering decanter centrifuge available can be mounted on a separate telescoping skid or on the drilling mud tank.

Solid Bowl Decanter Centrifuge Introduction

Solid Bowl Decanter Centrifuge (also called Solid Bowl Centrifuge
) is a type of centrifuge that uses the principle of sedimentation. It is normally used to separate solid-liquid, liquid-liquid, and solid-solid mixtures. Solid bowl centrifuges are widely used in various industrial applications, such as wastewater treatment, coal manufacturing, and polymer manufacturing.
