What is an Industrial Centrifuge

Introduction to an Industrial Centrifuge



An industrial centrifuge is a machine that uses the centrigugal force to separate liquid and solid particles or components of a liquid mixture. It is a extremely popular and effective solid-liquid extraction technique, and widely used in many fields, such as the chemical engineering, petroleum, food processing, pharmaceutical, mineral processing, carbon, water treatment,nuclear energy industry and shipbuilding, and other fields. Specifically, there are two main types of of industrial centrifuges: sedimentation centrifuges and filter centrifuges. The former is used to separate substances with different sedimentation coefficient and buoyancy density, which is driven by the strong centrifugal force generated by high-speed rotation of the rotor. The latter is used to separate the substaces of solids and liquids through the centrifugal force generated by the high-speed centrifugal drum (with apprapriate filter material).

How does an Industrial Centrifuge Work?

The centrifuge has a cylinder(drum) that rotates at a high speed, which is usually driven by an electric motor. After the suspension (or emulsion) is added to the drum, it is rapidly driven to rotate at the same speed as the drum, and the components within the mixtures are separated under the fuction of the centrifugal force and discharged separately. Generally, the higher the drum speed is , the better the separation will be. When the suspension containing fine particles is left still, the suspended particles gradually sink due to the action of the gravitational field. The heavier the particles are, the faster they sink.

What Industries Use Centrifuges?

As a common separation equipment, the centrifuge is widely used in the medical systems, university research, biopharmaceuticals, food and drug testing, petroleum, chemical, environmental protection and other fields.
