Feeder Screw

To achieve an optimum result during the production of pellets it is necessary for the raw materials to be dosed adequately and evenly. For this reason, PTN has developed its own feed systems ( feeder screw ).

The details make the difference in this feeder screw manufactured entirely from stainless steel. The geometry of the shaft flight guarantees a uniform product flow. For use as dosing and conveyor screw for meal and granulates.
