For the disposal of edge trims at extrusion lines and rewinding systems we equip the granulators with infeed systems. The infeed rollers can be designed:
- smooth (standard)
- knurled or
- grooved
They are wear protected in all versions.
For simple applications, the infeed systems can be equipped with rotary field magnetic motors. For applications with higher line speeds, we link the infeed speed with your line speed. The additional speed adjustment guarantees a very reliable operation and does not influence the extrusion and trim cutting process.
Advantages
High efficiency
- opening of infeed and cutting chamber without tools
- screen holder removable
- low cleaning time due to smooth, all-side machined surfaces
- high energy efficiency due to cutting geometry and EnergySave motor controller
Excellent regrind quality
- scissors cut with constand cutting circle
- stationary blade is mounted against hardened stop
- rotary blades adjustable outside of the granulator
- sealed design and low rotor revolution ensure quiet operation and low-dust regrind
High operational reliability
- separate infeed systems for each edge trim
- controlled adjustment to line speed for constant draw
- adjustable strippers prevent windings
- synchronous running of both infeed rollers
Individual features
- water cooled cutting chamber for temperature-sensitive material
- infeed rollers with different diameters and surfaces
- stand alone solution or integration into the production line
