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 and different die speeds. 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.
