Product description
Decanter Centrifuge General Description: Based on the more 30 years separator technics experience, we have developed and advanced the previous centrifuge and separator which keep more suitable for large sludge liquid product processing as well. Decanter Centrifuge: When separator operation is no longer feasible due to high proportions of solids in the suspension to be processed, decanters are used. Decanters are horizontal, solids-oriented, solid-wall scroll centrifuges.
The solid bowl decanter centrifuge consists of two horizontal concentric rotating elements contained in a stationary casing. The outer rotating bowl element is tapered so that the solids discharge from a smaller radius than the liquor. The inner element is a hollow hub screw conveyor with blade tips shaped to fit closely to the contour of the bowl. Decanter Centrifuge Separation Theorem 1. Feed slurry is introduced into the conveyor hub. As the feed accelerates to the machine speed, the slurry is delivered by centrifugal force into the rotating bowl by way of ports in the conveyor hub. 2. The solids settle through the liquor pool formed on the wall of the bowl. The solids are then conveyed, due to a slight differential between the screw conveyor and bowl, up the drying beach to the solids discharge ports. 3. The clarified liquors are discharge in the opposite direction from adjustable overflow ports.
