Screw Conveyor/Feeder

The Screw Conveyor/Feeder has been upgraded to the MTL Screw Feeder which features a smaller footprint and other improvements.

Product Overview

Metalfab's highly accurate, dependable Model DB2 volumetric screw feeder has only five moving parts - drive, coupling, 2 bearings and a screw. The large diameter inlet to the V-shaped trough, which helps insure complete filling of screw flights, provides feed accuracies of +/- 1 to 1 1/2%. When a Metalfab Posibin or Bin Activator is used to supply the feeder, even greater accuracies may be obtained.

A bin activator is recommended when feed rates are more than 1,000 cu. ft./hr. or non-free flowing materials are in process. Flight-type screws with through shafts are standard. Oversize ball bearings which are sealed and provided with grease fittings support the shaft. Operating noise levels are within OSHA requirements. All moving parts are guarded and the screw section is totally enclosed.
