PR Ribbon Flight Screw Feeders ensure uniform discharging and feeding of lime in special dosing plants from a silo into a dissolver or micro-feeding device.
A specialised version of the TU-type screw conveyor, configured in particular for use with hydrated lime, the PR-type Tubular Screw Feeder comes with a ribbon flight screw. For process reasons this screw feeder type is often equipped with a variable speed drive.
