Centrifuges are mechanical devices designed to separate components of a mixture based on their density by applying a centrifugal force. Widely used in industries such as pharmaceuticals, chemical processing, food and beverage, and wastewater treatment, centrifuges are essential for efficient solid-liquid or liquid-liquid separation. This guide provides a comprehensive overview of various types of centrifuges, conforming to ISO 10628-2 standards.
Centrifuges are represented in P&IDs with distinct symbols highlighting their operational principles:
| Symbol | Name | Description |
|---|---|---|
 | Centrifuge Pusher Type | A device for density-based separation using with a reciprocating pusher mechanism. |
 | Centrifuge Screw Type with Perforated Shell | A device for density-based separation with a perforated shell for dewatering applications. |
 | Centrifuge Separator Disc Type | A device that employs disc stacks for high-speed separation of liquid-liquid and liquid-solid mixtures. |
 | Centrifuge Skimmer Type | A device that is designed for efficient skimming of light fractions from liquids. |
 | Centrifuge with Perforated Shell | A device that features a perforated drum for separating solids from liquids in batch operations. |
 | Centrifuge with Solid Shell | A device that utilizes a solid shell for handling dense slurries and viscous materials. |
 | Decanter Centrifuge Screw Type with Solid Shell | A device that combines a screw conveyor and a solid shell for continuous separation of high-solid-content mixtures. |
 | High-Speed Centrifuge | A device that operates at extremely high rotational speeds for precise separation of fine particles. |
Centrifuges are used in a variety of applications requiring efficient separation processes, including:
