How are centrifuges classified by the walls of their spinning bowls?

Centrifuges are primarily classified into three general categories based on the construction of the spinning bowl that holds the material: those with a solid wall, those with a perforated wall, or those featuring a combination of both.1

• Solid-wall bowls: These are typically used for sedimentation processes, where suspended particles migrate toward the periphery and collect against the wall of the spinning vessel.1
• Perforated-wall bowls: Often referred to as basket centrifuges or centrifugal filters, these feature walls made of fine mesh screens or a series of screens supported by a heavier structure. They allow liquid to pass through while retaining solid particles, making them ideal for applications like drying clothes or processing crystals and fibrous materials.12

Additionally, centrifuges may be categorized by their operational process, such as continuous flow or batch processing.1
