Progress Pellet Mill

PTN’s pellet mill, a highly stable, robust and sophisticated pellet mill. More than 40 years of experience in development, engineering, and production ensures quality and continuity. The partially patented innovations offer a unique price/performance ratio.

A technological concept ensures an even distribution of the enormous mechanical forces on the heavy bearings of the solid main shaft and intermediate shafts. The stepped transmission via V-belts and timing belts permit the application of higher motor powers. Combined with the refined transmission, the robust frame guarantees a stable and vibration-free pellet mill during production.

Dependent on the type of the Pellet Mill several options are available.

  • Remote roller adjustment (ARA). Increases the efficiency and simplifies the adjustment of the rollers during production. No critical components in pellet chamber.
  • Quick die change system (QDC).* Improves efficiency by shortening die replacement time to approx. 15 min.
  • Roller Traction Control (RTC). Optimum non-slip adjustment of rollers during production. Extends the lifetime of dies and roller shells and increases the production efficiency.

Other options:

  • Roller head with 3 rollers*.
  • Forced feeder.
  • Turning device (for slowly turning the die to  the left or to the right)*.
  • Heated door/ feeding chute.

* This option is not available on all models
