Decanter centrifuge descriptions

DAGYEE decanter centrifuges help you with solid-liquid separation within one single continuous process. Stand out from the competition with high performance separation that results in extracted/clarified products of excellent quality and higher commercial value. Make a difference as you recover valuable raw materials, reduce energy consumption and lower footprint and waste management costs with our industrial decanter centrifuge machines and services.

How does a decanter centrifuge work?

The typical decanter centrifuge consists of several key components:

Cylindrical Bowl: The main rotating vessel where separation occurs
Screw Conveyor (Scroll): A helical screw that rotates slightly faster or slower than the bowl to transport separated solids
Feed Zone: Where the mixture enters the centrifuge
Discharge Ports: Separate outlets for liquid and solid fractions
Drive System: Motors and gearboxes that power the rotation

Decanter centrifuge advanced operation capabilities

Clarification

Clarification removes suspended solids from a liquid of lower density across a particle size range from 1 to 10,000 microns. By increasing centrifugal force, even submicron particles can be separated, making this process ideal for high-purity applications in chemicals, mining, and waste management.
Classifying
Through controlled reduction of residence time, the decanter achieves sharp separation cuts for particle-size classification down to the submicron range. This capability is essential for processes requiring precise particle distribution and custom engineering solutions.
Liquid/liquid separation
The efficiently separates immiscible liquid phases of different densities, with or without solids present. This is critical for oil recovery and industrial wastewater treatment, where mechanical dewatering and centrifugal separation reduce reprocessing and disposal costs.
Thickening
Fine solids separated from the liquid can be thickened in a hindered settling mode, utilizing the cylindrical section of the bowl for maximum compression. This improves solids handling and reduces downstream load, contributing to operational efficiency.
Compression and dewatering
Compactive dewatering combines drainage and compression to achieve a higher degree of dryness, even with compressible solids. The degree of dewatering depends on solids characteristics, machine settings, and required dryness levels. Optimized conveyor and cone geometry, along with differential speed control, ensure stable discharge of pasty or shear-sensitive solids—key for waste management and cost reduction.
Counter-current washing
Integrated washing systems allow efficient, cost-effective removal of contaminants by separate discharge of wash liquor over multiple sections. This reduces chemical and water consumption, aligning with sustainability and process optimization goals.
Mixing and re-suspension
Special discharge geometries enable solids to be mixed with liquid directly at the outlet, eliminating the need for additional mixing vessels. This feature simplifies plant design and enhances operational efficiency.
Automation and innovation
Control systems for smart operation
Control systems stabilize separation quality, automate setpoints, and provide diagnostics that support predictive service strategies. As the “brain” behind the process, strengthens industrial automation and helps maintain equipment reliability through better visibility, alarms, and optimization tools.
Engineered for tough conditions
A broad choice of materials of construction, wear protection, and sealing options extends service life in abrasive or corrosive duties. Features like CIP, optimized bearings and seals, and gas-tight/pressurized casings are designed to lower maintenance effort while keeping performance high.
Options that boost performance
Depending on application, It can be equipped with energy-recovery weir plates, specialized feed systems to reduce particle breakage, and multiple drive/gearbox configurations—each selected to match duty conditions and performance targets.

Decanter centrifuge key features

The Flottweg Simp Drive regulates the differential speed of the screw conveyor according to the load. If the differential speed is too low, there is a risk of blockage. With the correct setting, the system protects against overload and blockage. If the separation space is to be sealed against the atmosphere, Flottweg offers various sealing systems: atmospheric centrifuges, vapour-tight centrifuges, inert centrifuges. Various monitoring systems control vibration and speed. Critical operating conditions can thus be avoided and relevant safety standards complied with. Optionally, the storage temperature of the decanter centrifuge can also be monitored to prevent storage damage.
