A feedwell system for delivering a slurry (for example a bituminous slurry) to a separation vessel (for example a primary separation vessel) includes a feedwell barrel with an inlet for receiving the slurry, internal baffles, and a bottom outlet. A downpipe extends from the bottom of the barrel directing the existing slurry onto a deflector plate …

Conversely, trapezoidal-deck separators are recommended for heavy-end separations, requiring the removal of a relatively small amount of heavy material. Fundamentally, the operation is the same as it was at the turn of the century. Part I of this series provides a high-level overview of how gravity separators work. Learn more about gravity ...

feedwell. The open feedwell exit provides a large surface area for aggregate throughput, reducing velocities and turbulence as the slurry exits the feedwell, minimising the aggregate breakage that can occur in the closed-bottom feedwells. Reduced shear-induced breakage increases settling rates, improves clarity and maximises density.
