Industrial Principle And Application Of Decanter Centrifuge

May 18, 2020

The decanter centrifuge is a machine that uses centrifugal force to separate the solid-liquid mixture in different materials. Under the action of centrifugal force, the material tends to the drum wall, the liquid phase passes through the filter hole of the drum through the filter medium covered in the drum, and is thrown toward the cabinet space, falls into the chassis of the machine body, is discharged through the liquid outlet, and solid Phase materials remain in the drum, thus completing the entire separation process.


The decanter centrifuge has a wide range of applications: for solid phase liquid volume concentration of 10-60%, solid particles with an equivalent diameter of ≥80μm solid particles or suspension of fibrous materials can generally be used for solid-liquid separation or centrifugal dehydration. It can greatly reduce the cost of thermal drying of materials, and even save the drying process. The decanter centrifuge is continuously feeding and discharging, and is equipped with washing function. Continuous work, large processing capacity, reasonable power allocation and low energy consumption. The decanter centrifuge has a compact structure, small footprint, easy installation and maintenance, and the whole machine can be operated in a closed environment.


The decanter centrifuge generally handles lees, fermentation broth, sewage, etc.
