Custom Decanter Separator

The decanter centrifuge is a type of machinery that performs continuous separation of materials with density differences in suspensions using the centrifugal sedimentation principle. Its basic principle is as follows: The bowl and feeding screw rotate at high speed with a certain differential speed between them. Materials are continuously introduced through the feed tube into the inner cylinder of the spiral material pusher, then enter the bowl after acceleration. Under the centrifugal force field, the heavier solids will deposit on the bowl walls and form residue layers. The spiral material pusher will continuously push the deposited solids to the tapered end of the bowl and discharge them from the machine through the residue outlet after dehydration in the drying area.

It is widely used in industries such as the chemical industry, light industry, medicine, food, environmental protection, etc.


  • Hydraullc driving

    ln hydraulic driving, the bow and screw are driven by the variablefrequency motor + frequency converter + hydraulic mator.

    Under the hydraulic driving mode, the difterential speed betweenthe bow and screw can be adjusted precisely through the hydraulic motar. When running at a very low differential rotation speed, the precision and stability are high-quality to those under other driving modes. When the bowl runs normally, the bowl and screwwill run at certain constant speeds. Once the load of the spiral material pusher increases, the hydraulic motor will adjust the spiral material power to run at an accelerated speed to avoid material blocking. When the machine is stopped for washing due to material blocking, the hydraulic system can separately drive the spiral material pusher to run so as to greatly improve washing maintenance efficiency.


  • Single-motor driving

    ln single-motor driving, the bowl and screw are driven by onevariable frequency motor + frequency converter. This driving mode is simple, the operation is convenient, and the manufacturing costs are relatively low.

    Single-motor driving is mainly used for materials with a constant solid content and those having no strict requirements for the water content of discharged solids. As there is no necessary differentialspeed adjusting mechanism, the differential speed between bowland screw can only be realized through changing the gear transmission ratio or the rotation speed of the bowl.


  • Double-motor driving

    ln double-motor driving, the bowl and screw are driven by two variable frequency motors + two frequency converters.

    Under the double-motor driving mode, the differential speed between the bowl and screw can be adjusted through simple adjustment of the rotation speed of the motor. Therefore, this driving mode is widely used for materials without a constant solid content and those having strict requirements for the water content of discharged solids.

    After entering the cavity of the spiral material pusher through the feed tube, the suspensions will enter the cavity of the bowl through the material vent. The solids after sedimentation will move to the small end af the bow under the pushing action at the differential speed of the screw, and be finally discharged from the solid discharge port. Under the action of centrifugal force, the liquids will form a hollow liquid ring and move to the longer end of the bow. After running over the adjustable overbaffle, they will be discharged from the liquid outlet under the action of gravity.

Key Features and Advantages of Decanter Centrifuges

Decanter centrifuges excel in continuous operation, which is one of their most significant advantages. In industries where large quantities of material need to be processed without interruption, these machines are indispensable. The continuous operation allows the centrifuge to process materials without halting for each batch, thereby enabling higher throughput and a more consistent production rate. This feature is particularly crucial in industries such as wastewater treatment, oil recovery, and food processing, where time is a critical factor in maintaining production schedules. For instance, in wastewater treatment, continuous operation allows the separation of solids from effluent water without having to stop and restart the process. This results in steady processing and ensures that the treated water is consistently compliant with environmental regulations. In the food and beverage industry, decanter centrifuges are used to clarify juices and extract valuable liquids, all while maintaining continuous operations. This high throughput allows for economies of scale, meaning that large quantities of product can be processed efficiently and cost-effectively. By reducing downtime, decanter centrifuges ultimately help lower labor and operational costs, increasing profitability for industries that depend on high-volume processing.
