Benefitsl Very stable, vibration-free and near-silent pellet mill.l Large die surface area and roller diameter.l Large motor powers.l Variable die speed.l Suitable as two- or three-roller pellet mill.l Longer lifetime of die and rollers.l Conical die fitting.l Central greasing system.l Longer lifetime of main shaft bearings.l Integrated pneumatic quick-dump chute.l Minimal maintenance costs.l Easy to clean.l Simple design.l Central electrical connection box.

Product description:A sophisticated 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 permits the application of higher motor powers. Combined with the refined transmission, the robust frame guarantees a stable and vibration-free pellet mill during production.

Automatic Roller Adjustment (ARA)PTN’s patented automatic roller adjustment, in which hydraulic precision is combined with mechanical stability, increases the efficiency and simplifies the adjustment of the rollers during production. The eccentric roller shafts, in combination with the automatic roller adjustment, extend the lifetime of dies and roller shells by up to 15%.

Roller Traction Control (RTC)PTN’s innovative technology for an optimum, non-slip adjustment of the rollers during production. The roller traction control (RTC) extends the lifetime of dies and roller shells and increases the production efficiency.
