Decanter centrifuge, a very unfamiliar sounding name, seems to be a machine from the future world. In fact, it is a device widely used in industrial production, mainly for the separation of solid-liquid two-phase substances. In other words, it is an important equipment that can greatly improve production efficiency and reduce production costs.
Working Principle
Decanter centrifuge principle seems complex, in fact is simple. The working principle of decanter centrifuge is based on the principle of centrifugal sedimentation. In the process of operation, the drum and the spiral rotate in the same direction at a certain differential speed. The material is continuously introduced into the inner cylinder of the feed screw through the feed pipe, and then accelerated into the rotating drum. Under the action of centrifugal force field, heavy solids are deposited on the drum wall to form a sediment layer, which is pushed from the spiral to the end of the drum cone. The lighter liquid phase forms the inner liquid ring and is discharged from the overflow port at the big end of the drum. This continuous feeding, separation, washing and unloading process enables the decanter centrifuge to have an efficient and continuous production capacity.

Characteristics And Advantages
Compact structure: Decanter centrifuge compact design, small footprint, easy to install and maintain.
Continuous operation: It can continuously feed, separate, wash and discharge at full speed, which greatly improves production efficiency.
Smooth operation: Advanced transmission and control system is adopted to ensure smooth operation of equipment and reduce noise and vibration.
Strong adaptability: suitable for the separation of a variety of materials, especially for suspensions containing solid particles with particle size greater than 0.005mm and concentration range of 2-40%, the separation effect is significant.
Large processing capacity: decanter centrifuge with large length-diameter ratio has stronger processing capacity and can handle a large number of materials.
Easy maintenance: Modular design makes maintenance and replacement of parts easy and fast.
Multiple Applications
Decanters also play an important role in many areas you might not expect. Widely used in chemical, light industry, pharmaceutical, food, environmental protection and other industries. For example, in the field of environmental protection, decanter centrifuges are used for sewage treatment, which is mainly used for dewatering the sludge generated in the industrial and civil sewage treatment process, effectively separating the solid and liquid in the sewage, and improving the efficiency and quality of sewage treatment. In the field of food, decanter centrifuges are used for the refining of juice, milk and other foods, so that we can enjoy more pure and delicious food. Decanter centrifuge is more and more widely used in the field of environmental protection because of its characteristics of large capacity, high degree of automation and good dewatering effect.
Precautions For Use
Comply with the operating manual: Before operating the decanter, you must carefully read and comply with all requirements in the operating manual.
Adjust parameters: According to the material properties and separation requirements, reasonable adjustment of spiral speed, centrifugal force and centrifugal time and other parameters
Safe operation: During the operation of the equipment, do not open or close the cover of the centrifuge at will to prevent accidents. At the same time, it is forbidden to put hands or other objects inside the centrifuge.
Regular inspection: Regularly check the automatic cutting device and monitoring system to ensure the normal operation of the equipment. At the same time, check the integrity of the drum, motor and support frame, and whether the motor is running in the correct direction.
Maintenance: After use, the inside of the centrifuge should be cleaned in time to avoid the contamination residue affecting the next use. At the same time, regularly check the lubrication system and sealing performance of the equipment to ensure long-term stable operation of the equipment.
Future Development Trend
With the enhancement of environmental awareness and the increasing demand for high efficiency, energy saving and environmental protection equipment in industrial production, decanter centrifuges have broad prospects for development. In the future, decanter centrifuges will pay more attention to the improvement of intelligent, automated and environmental performance to meet the needs of different industries for centrifugal separation technology. At the same time, with the continuous emergence of new materials and new technologies, the performance of decanter centrifuges will be improved and improved.
