PTF triple feeder
The PTF triple feeder is unique due to the combination of a standard central drive with a pre-reduction gearbox.
PTF triple feeder
The triple-stage distribution gearbox ensures that a single drive can operate both the dosing screw and the two agitator shafts. The dosing screw and the two agitator arms rotate at different speeds, but always in a fixed ratio.
The agitators rotate very slowly to prevent product damage and rotate around the dosing screw. This design ensures that the dosing screw is optimally filled with a constant bulk density, guaranteeing highly accurate volumetric dosing.
The PTF is particularly suitable for very poorly flowing products. Due to the large dosing chamber, the opening to the hopper is very wide, minimizing or virtually eliminating the risk of bridging above the dosing chamber. Because the agitators rotate around the dosing screw, there is no risk of bridging between the agitators and the dosing screw — a phenomenon often seen in conventional dosing units.
