Decanter centrifuges are used in the chemical, oil, food and waste water industries to seperate solid materials from liquid slurries. A solid bowl decanter consists of two horizontal concentric rotating elements contained in a stationary casing. The outer rotating bowl element is tapered so that solids discharge from a smaller radius then the liquor. The inner element is a hollow hub and helical screw conveyor with blades profiled to fit closely to the contour of the bowl.
Feed slurry is introduced into the hollow hub by either pump or gravity, and as this automatically accelerates to machine speed the slurry is transferred by centrifugal force into the rotating bowl via discharge ports, where solids settle through the liquor pool formed on the wall of the bowl. There is a slight differential speed between the rotation of the bowl and that of the screw conveyor, which allows the solids to be conveyed continuously along the bowl wall, out of the pool and up the tapered drying beach towards the final solids discharge ports. As for the clarified liquor it discharges continuously in the opposite direction through adjustable overflow ports.
Employed as a classifier, the solid bowl decanter effects sharp size cuts of solids in liquor suspension, and can be used to process materials between 1-50 microns in size. Manufacturers of decanter centrifuges include Broadbent, Bird, Sharples, Alfa Laval, Westfalia, Humboldt, Flottweg. Please see below a list of decanter centrifuges we currently have in stock.
