GN Decanter Centrifuge Bowl & Scew Conveyer

Aug. 18, 2012 - PRLog -- Bowl and Screw conveyer are two main component in decanter centrifuge. the quality and design of bowl and scroll directly related to the life and performance of the decanter centrifuge.The key to good decanter performance lies in the efficient ,effective scrolling of the sedimented solids,The design of the screw conveyor is therefore crucial. GN has the expertise needed to match the demands involved in specific industrial processes with specific configurations of flight pitch,lead angle and differential speed,in order to secure the best possible results.

Bowl.
The bowl has a cylindrical/conical shape and rotates at a pre-set speed optimally adjusted to the application. The slurry rotates with the bowl at the operating speed and forms a concentric layer at the bowl wall. The solids contained in the product are packed against the bowl wall by centrifugal force.The length of the cylindrical bowl section and the cone angle are selected to meet the specific requirements of an application.

Screw conveyer.

The screw conveyer rotates at a slightly different speed than the bowl and conveys the separated solids toward the conical end of the bowl.This differential speed determines the residence time of the solids in the bowl. Residence time is a critical factor for cake dryness. It can be adjusted by changing the differential speed of the scroll thus providing optimal separation.

The bowl and scroll body of GN centrifuge are made of high-strength centrifugal duplex stainless steel casting. All wear-prone areas of the centrifuge-feed zone,solids discharge,bowl and scroll are protected by hard surfacing.
