Centrifuge is a machine that uses centrifugal force to accelerate the separation of different materials that need to be separated. Centrifuges are widely used in chemical, petroleum, food, pharmaceutical, mineral processing, coal, water treatment and shipbuilding sectors. There are several kinds of centrifuges, and different centrifuges have different applications. So knowing how to select a centrifuge is very essential, which could effect the working effectiveness of concentrating or extracting substances. The following are the instructions for centrifuges and their applications:
- Decanter centrifuge
Decanter centrifuge is to separate substances with sedimentation coefficient and buoyant density through being accelerated by strong centrifugal force that is produced by high-speed motor. Decanter centrifuge is suitable for a wide range of materials. For example, the large viscosity of the material, and the small solid-phase particles can achieve the requirement of solid-liquid two-phase separation by increasing the centrifugal force.
- Filter centrifuge
Filter centrifuge is is to pull out the liquid-phase substances by strong centrifugal power that is produced by high-speed rotary drum. When the liquid-phase substances are pulled out, the solid-phase substances will stay in the rotary drum. The filter centrifuge is suitable for industrial dehydration in which the viscosity of the material is small, the solid phase particles are not easily deformed (such as crystal), and the solid phase particles are large and small batches are produced.
