big bowl centrifuge

Comparing with the most commonly used 14 inch decanter centrifuges, the GNLW452 and GNLW453 Decanter Centrifuges of 18 inch bowl and GNLW553 decanter centrifuge of 22 inch bowl are already called big bowl centrifuges. In this case, the newly on show GNLW764A-VFD Decanter Centrifuge could be a giant centrifuge, because the bowl diameter is 30 inch while the length-diameter ratio is 4.4 to one.

This design is suitable for handling the large capacity with a single unit of centrifuge. And the special design and best material chosen makes the GNLW764 decanter centrifuge to have a good performance and longer service life.
Besides GNLW764A-VFD decanter centrifuge, GN also has designed GNLW554D-VFD decanter centrifuge, which is also of large length diameter ratio up to 4, it is quite suitable for the waste water treatment projects.
