MTL Standard Screw Conveyor


MTL Screw Feeder/Conveyor

The MTL Screw Feeder/Conveyor is an upgrade of the DB2 Screw Feeder which incorporates the latest technology including a smaller footprint. The DB2 is still available upon request.

Overview

Metalfab's highly accurate, dependable Model MTL Volumetric Screw Feeder/Conveyor has only five moving parts - drive, coupling, two bearings, and a screw. The combination of a large inlet and a U-shaped trough help ensure complete filling of screw flights and 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 100 cu. ft./hr. or non-free flowing materials need to be metered. Flight-type screws with through shafts are standard. Oversize 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.
