Industrial centrifuges separate or purify large quantities of materials using centrifugal force. They spin samples at high speeds to separate components based on density, size, or shape. There are three main types - decanter, filter, and sedimentation centrifuges. Decanter centrifuges continuously separate solids from liquids or two immiscible liquids. Filter centrifuges retain particulates while allowing liquid to pass through. Sedimentation centrifuges accumulate solids around the bowl wall while liquid exits through an output passage. Industrial centrifuges are used across industries such as fuel processing, water treatment, chemicals, pharmaceuticals, mining, and food/dairy processing.
