MTP Screw Feeder

MTP For Difficult Materials

The MTP is an upgrade of the DB1T Volumetric Screw Feeder which incorporates the latest technology including a smaller footprint. The DB1T is still available upon request.


Metalfab's MTP Volumetric Screw Feeder provides all the features available with the standard Metalfab feeders but is designed for the handling of more difficult to feed materials. To solve these problems, the MTP has been designed with greater clearances and larger agitator/conditioner screws (including one for the 6" size).


  • Accuracy: ±1 to 1-½% (one minute samples)
  • Screw Sizes: 3", 4", 6" diameter; agitator/conditioning screws 8" and 10"
  • Feed Rates: 6 to 550 cu. ft./hr max.
  • Motor: AC Variable Frequency drive is standard. Options available.

Operating Characteristics

  • Handles difficult to meter materials such as film scrap, wood chips, filter cake, asbestos, fibrous products, and other materials which present vexing problems
