Screw Conveyor Disharge Door
Screw Conveyor Disharge Door

P&L Specialties has developed a pneumatically operated Sliding Discharge Door for screw conveyors that really works! The doors are watertight and perform flawlessly. This industry innovation is the result of hundreds of hours of R&D prior to active service.

P&L Specialties' Sliding Doors offer a real alternative to using knife gate valves. Our doors reduce capital costs, maintenance expenses, reliability problems, and the dead zones associated with knife gate valves.

The Sliding Discharge Door fits tightly to the conveyor profile, thereby eliminating product build-up. The result is gentler conveyance with the door closed, and zero material build-up.

Our engineering department can retrofit the Sliding Door to existing screw conveyors as well as incorporate them into new systems. Our Sliding Door design is watertight, low maintenance, and cost effective. This technology is proven in the field and we have numerous units in service.

The Sliding Discharge Door is a P&L Specialties' proprietary design.
