Screw Feeders & Chutes Replacements

Spec Engineering improved the mass flow capacity and problematic flowability of part of this process in this plant by replacing two screw feeders and a critical set of screw feeder discharge chutes that charge wet cake material from centrifuges into a downstream mixer. Key to the success was the redesign of these discharge gravity chutes in an area of tight tolerances and challenging interferences, requiring smooth product flow via gravity.

A new system was developed that upgraded the capacity of the screw feeders, moved the screw feeders closer together, cored new penetrations through the concrete floor to the lower deck, and incorporated a custom, more vertical, multi-chute connection into the mixer. These new chutes included special clean-out ports with high level sensors to indicate any material back-up in the chutes.
