As for horizontal screw decanter centrifuge

A decanter centrifuge is an excellent drilling mud solids control equipment for separating liquid and solid mixtures in the field of oil drilling mud solids control. Industrial work and water processing plants are often tasked with purifying substances with variable amounts of solid material, and a decanter centrifuge is engineered to remove any and all contaminates from sewage and effluent sludge. Decanting centrifuge is also capable of separating disparate fluids such as weighted or non-weighted oil and water based liquids. For example, those in the beverage industry commonly employ decanter centrifuges to extract juices. Utilizing basic gravitational force, the centrifuge divides the denser, weightier solids from the lighter, effluviant liquid. Consequently, decanter centrifuges are utilized by a variety of industries with applications extending from water processing to the manufacturing of stainless steel.

The two primary types of Decanter centrifuges are:

1. Solid Bowl Decanter Centrifuge
This centrifuge is encased in a shell comprised of two layers. The outer layer has a tapered aperture which allows solids to discharge as the bowl rotates. The inner layer is a hollow case molded to match the outline of the bowl. The resulting centrifuge mitigates the amount of moisture in the cake and produces material with a higher quality centrate. Solid bowl decanters are manufactured with two or three phases, and are generally inexpensive to purchase and maintain. Their environmental impact is minimal and in full compliance with CE regulations.
2. Screen Bowl Decanter Centrifuge

Ranging in 160mm to 1400mm in diameter, screen bowl decanter centrifuges are engineered to separate materials with better overall washing efficiency. Primarily used in separating polyolefins and minerals, these decanters work in multiple phases, starting with sedimentation and clarification before moving on to the water removal process.

The working environments of Decanter centrifuge:

1.Oil and Gas Drilling is the first environment for centrifuge working in the drilling industry. Decanter centrifuge spec is very strict for this environment. Normally IECEX/ATEX explosion proof standard is required for developed countries;
2.Drilling waste management industry is growing very fast and popular in Latin America and middle east. Cutting Dryer, Hi-G dryer and decanter centrifuge is the core equipment for drilling waste management system;

3.CBM/HDD drilling is the new markets that require decanter centrifuge. It was seldom that clients need centrifuge to save cost but more and more clients like to working a centrifuge for better performance.


There are several types of decanter centrifuges currently utilized in the industry, the most common of which are vertical, horizontal and conveyor centrifuges. The principle behind a solid control decanter centrifuge is based on the theory of gravitational separation. For example, if you fill a glass with a mixture of mud and water, over time the weight of the mud will cause it to settle down at the base of the glass. With the mud congealed at the bottom, the water will be forced upwards, creating a clear separation between the two.
