Crumbler HE-serie

The PTN crumbler technology is based on two large, independently driven rollers. That ensures an optimum result of minimum fines with maximum crumble.

An integrated control valve ensures an even flow to an axially riffled proportioning roller, manufactured from solid steel.

Large-scale axially and radially riffled crumble rollers rotate, at equal speeds in opposite directions, and cut the pellet to a crumble.

Using accurate measurement, the large 300mm crumble rollers guarantee an optimum result. The remote roller adjustment system increases the efficiency and simplifies the adjustment of the roller distance during production.

High Efficiency Line

The development of our new High Efficiency line (HE) concentrated not only on higher performances and a more hygienic design but also lower energy consumption. The new HE line gives excellent access to all maintenance areas.

With this HE line PTN is making a new step forward.

High Efficiency Advantages

  • More capacity with same energy level.
  • Frequency controlled dual rotation feeder (by-pass function),frequency not included.
  • Rollers are exchangeable from front and the sides.
  • 50% more revision options of the rollers.
  • Easy maintenance access.
