Features of the FW400
Flottweg Decanter Scroll
The decanter scroll conveys the solids deposited against the bowl wall by centrifugal force toward the conical end of the bowl at an optimal differential speed. This determines the residence time of the solids and influences the total dry solids. Various scroll designs allow for flexible adaptation to different products and processes.
Differential Speed
The differential speed between the decanter bowl and the screw conveyor determines the retention time and compaction of the solids, and thus the total dry solids. It is variably adjustable to ensure optimal separation results for varying product characteristics.
Pond Depth
The pond depth affects the retention time of the liquid and thus the length of the clarification and drying zones. By adjusting the weir plates while the system is at a standstill, this can be specifically adjusted to optimize separation performance.
Lubrication
To ensure the service life of decanter centrifuges, Flottweg offers specially formulated lubricants. The Endrive gear oil ensures long-lasting drive performance with excellent wear protection and helps save energy. The Sympact roller bearing grease protects friction points and increases the service life of the bearings.
Recuvane®
The Recuvane® system lowers the operating costs of a decanter centrifuge by reducing energy consumption by 10 to 20%. It reclaims the rotational energy lost during the pressureless discharge of the liquid and assists the main drive. The mechanically robust system allows for the adjustment of multiple pond depths and typically pays for itself within a few months to two years.
