Industrial Decanter Centrifuges

An industrial decanter centrifuge is a specialized centrifuge used in various industries for separating solid and liquid components from a suspension or slurry. It employs the principles of centrifugal force to achieve the separation.

The decanter centrifuge consists of a rotating bowl, a conveyor screw, and a differential speed drive system. The suspension or slurry is fed into the rotating bowl through an inlet at one end. As the bowl spins at a high speed, the centrifugal force causes the solid particles to settle against the bowl wall, while the liquid phase forms a clear layer in the center.

Construction and Materials: Decanter centrifuges are constructed using robust and corrosion-resistant materials to withstand the demanding conditions of industrial applications. The bowl and conveyor screw are made of stainless steel or other durable alloys.

 

Variable Speed Control:  Industrial decanter centrifuges have variable speed control mechanisms, allowing operators to adjust the rotational speed of the bowl and the conveyor screw. This feature enables fine-tuning of separation performance and the ability to handle different feed materials.

 

Differential Speed Adjustment:  The ability to adjust the speed difference between the bowl and the conveyor screw is crucial for controlling the residence time of the solids in the centrifuge. It helps in optimizing dewatering, separation efficiency, and the moisture content of the discharged solids.

 

Automatic Operation and Control:  Our industrial decanter centrifuges are equipped with advanced automation features. These can include programmable logic controllers (PLCs) and human-machine interfaces (HMIs) that enable operators to set and monitor various operating parameters such as speed, feed rate, and discharge settings.

 

Solids Discharge System:  Industrial decanter centrifuges are equipped with mechanisms for efficient and controlled solids discharge. This can involve adjustable discharge ports, scraper blades, or pneumatic systems to ensure smooth and continuous removal of the separated solids from the centrifuge.

 

Safety Features:  Safety is a critical consideration in industrial processes. Decanter centrifuges come with safety features such as emergency stop buttons, overload protection systems, vibration monitoring, and interlocking mechanisms to prevent unsafe conditions and protect both operators and the equipment. 

 

Efficient Solid-Liquid Separation:  Industrial decanter centrifuges are designed to provide efficient separation of solid and liquid phases. They incorporate optimized bowl geometries, advanced scroll designs, and effective discharge systems to maximize separation performance, minimize liquid carryover, and enhance dewatering capabilities.

 

Size and Capacity Range:  Our decanter centrifuges are available in a range of sizes and capacities to accommodate different process volumes and requirements. 

 

 

Decanter centrifuges are commonly used in industries such as wastewater treatment, oil and gas, chemical processing, food and beverage, and mining. They are effective in separating solids from liquids, recovering valuable materials, dewatering sludges, and reducing the volume of waste.

 

Wastewater Treatment: Decanter centrifuges are widely used in municipal and industrial wastewater treatment plants for dewatering sludge, separating solids from liquids, and reducing the volume of waste.

 

Oil and Gas Industry: In the oil and gas sector, decanter centrifuges are used for various applications, including crude oil clarification, sludge dewatering, and solids control in drilling mud.

 

Chemical Processing: Decanter centrifuges are employed in chemical processing for clarifying process liquids, recovering valuable products, and separating solids from liquids.

 

Food and Beverage: They are utilized for processes like juice clarification, vegetable oil extraction, and dewatering of food processing by-products.

 

Mining and Minerals: Decanter centrifuges are used in mining operations for dewatering tailings, recovering valuable minerals, and separating fine particles from suspensions.
