“SF” Volumetric Screw Feeders – Details

Volumetric Screw Feeders are used to control the flow rate of bulk material from a bin or hopper. They are designed to be flood fed, so that regardless of the amount of material in a hopper above the inlet, the outlet rate will remain consistent. Screw feeders are available to feed a wide range of materials.

Essmueller screw feeders are available in standard trough lengths, and in sizes to suit almost any need. They are available in single, double, triple and live bottom configurations. Multiple screws are used to control the flow rate of bulk material that tends to bridge a bin or hopper. Live bottom screw feeders are designed to be mounted under bins to control the flow rate of material that tend to pack or bridge. Tapered pitch or variable pitch screws are used in screw feeders to draw the bulk material evenly from all areas of inlet opening. CEMA standard components are selected based on the material to be handled.
