In the high-throughput sector, industrial centrifugation differs significantly from its laboratory counterpart. Unlike lab centrifuges, these industrial counterparts lack individual sample vessels and instead utilize a solid bowl or, in certain scenarios, a perforated basket as the rotor. Industrial centrifugation design permits the continuous feeding of materials into the spinning bowl, essentially facilitating in-line centrifugation.

High-speed industrial centrifugal separation is categorized into two main types: two-phase centrifugation and three-phase centrifugation. "Two-phase" centrifugation distinguishes itself by segregating mixed materials into a "solid phase" and a "liquid phase." Conversely, a "three-phase" Decanter Centrifuge divides the fluid into two liquid phases (one usually "heavy," such as water or water-based, and the other "light," typically oil), in addition to a solid phase.

a) The shape of the rotor vessel makes industrial centrifuges different

In the realm of industrial centrifuges, such as those incorporating a tubular bowl or a horizontal "screw" decanter centrifuge, the sorting of materials during separation is primarily determined by the shape of the rotor vessel. 

Solid particles of greater density accumulate on the rotor walls, exiting from one end, while the less dense liquid exits from the other end. This mechanism of new centrifuges can be likened to the functioning of a disc stack. It is where the arrangement of bowl internals and the geometry of the discs play a pivotal role in material separation and sediment collection.

b) Aligning centrifuge speed with the vessel makes industrial centrifuges different

Diverging from conventional designs, the "scraper bowl" centrifuge operates uniquely. In this high-performance, high-speed two-phase centrifuge, a vertical rotor maintains solid material throughout the process cycle. A feed pump of Dewatering Centrifuge propels mixed liquid into the spinning rotor, aligning its speed with the vessel. 

Centrifugal force expels solid particles from suspension in the liquid, keeping them against the rotor walls. The ensuing clean liquid drains from the bottom of the vertical rotor. During the intermittent "scrape cycle," the feed pump ceases operation, and a blade collects all captured solids against the bowl's interior.

c)  Easy repair makes industrial centrifuges different

Users have historically steered clear of scraper bowl centrifuges due to maintenance complexities. This avoidance is linked to older scraper bowl designs that employed redundant motor and drive-train configurations, necessitating intricate clutch interlocks and frequent servicing. 

However, the maintenance challenge is over with new centrifuge designs. Now, centrifuge Gearbox Repair costs less for industrial centrifuges. Built from the ground up, new centrifuge designs ensure hassle-free and dependable operation with minimal involvement from operators.
