Help companies fully understand the value of decanter centrifuges
What is a decanter centrifuge?
Decanter centrifuge, also known as horizontal spiral discharge sedimentation centrifuge (Decanter Centrifuge), is a device that uses centrifugal force to separate solid particles in a suspension from liquid.
Working principle:
High-speed rotation forms a centrifugal field
The decanter centrifuge forms a strong centrifugal force field with several thousand times the acceleration of gravity through the high-speed rotation of the drum, so that the solid particles in the suspension quickly settle to the inner wall of the drum.
Automatic slag discharge by screw conveyor
The built-in screw conveyor rotates synchronously with the drum at a certain differential speed, continuously pushing the deposited solids to the slag outlet to achieve uninterrupted slag discharge.
Main structure:
Drum: used for rotating separation of materials, determines the processing capacity and separation effect;
Screw conveyor: automatically pushes sediment;
Differential: controls the speed difference between the drum and the screw;
Machine base, electronic control system: used to support, control and protect the operation of the equipment.
Core advantages:
Automatic and continuous operation, saving labor;
Compact structure, small footprint;
Enclosed operation, environmental protection and pollution-free;
Differential speed is adjustable to cope with complex working conditions;
Low maintenance cost and long service life.
Application fields of decanter centrifuge
Decanter centrifuge is suitable for treating various suspensions with solid content between 0.5% and 40%, and is widely used in the following industries:
1. Municipal sewage treatment
Used for dehydration of urban sludge, reducing water content, and reducing the burden of sludge transportation and disposal;
Improve treatment capacity and meet the needs of intelligent transformation of sewage plants.
2. Industrial wastewater treatment
Wastewater treatment in chemical, electroplating, papermaking, printing and dyeing industries;
Excellent adaptability to highly corrosive and highly viscous materials.
3. Food and beverage processing

Questions and Answers
Q1: What types of materials are suitable for horizontal screw centrifuges?
A: It is mainly suitable for suspensions with a solid content between 0.5% and 40%, especially suitable for:
Particle size greater than 2μm;
Material with strong viscosity and difficult to filter;
Scenarios that require continuous large-scale separation.
Q2: Is the equipment maintenance complicated? How often is it maintained?
A: The maintenance of horizontal screw centrifuges is relatively simple:
Check the operation of the motor and transmission system every day;
Check the lubricating oil level and filtration every week.
How to choose a suitable decanter centrifuge?
1. Processing material parameters
Solid content, particle size, corrosiveness, viscosity, etc.;
Whether dosing, heating, constant temperature control and other functions are required.
2. Processing capacity requirements
Clearly define the daily or hourly processing volume;
Leave a 20%-30% expansion margin to avoid overload.
3. Equipment material selection
Ordinary stainless steel (SS304/316): suitable for neutral or weakly corrosive materials;
Duplex steel, Hastelloy: suitable for highly corrosive scenes;
Whether the drum and spiral blades are hardened and wear-resistant.
