Ferrum Innovation - Integrated thickener
08. Aug 2017
The integrated thickener developed and patented by Ferrum saves space and costs.
Pusher centrifuges require a sufficient solids concentration of the suspension to guarantee safe and constant operation. Furthermore, the pusher centrifuges run smoother and with minimum vibrations if the suspension shows optimum and constant solids concentration.
To ensure such process conditions additional thickening of the suspension upstream of the centrifuge is often necessary. This requires the installation of additional equipment, e.g. static thickener, hydrocyclone or curved sieve, is usually required.
Several years ago, Ferrum developed and patented the integrated thickener which is installed inside the centrifuge as an alternative. Under certain process conditions, the necessity of a separate external thickener is eliminated. This saves space and costs. At the same time, the centrifuge runs more stable and with less vibrations.
Sketch: Ferrum integrated thickener for pusher centrifuges
The Ferrum integrated thickener is installed in the feed area of the centrifuge and is cone-shaped so that the cake slides independently, by centrifugal force, over the filter surface. Due to thin layer filtration the filter resistance is substantially lower than with cake filtration, i.e. the filtration performance in the feed area is significantly higher than for a standard pusher centrifuge. In this way, the solids content after the thickening cone can be increased and normal cake formation is possible.

The integrated thickener has been further developed to allow different, project specifically designed filter media to be applied. There are suitable solutions even for corrosive and/or highly abrasive applications.
Further functions such as classification (deliberate separation of a fine fraction) or an intensive product washing within the feed area are, under certain process conditions, also possible.
