Product details

The heart of all Neuenhauser screw mills are the three slow rotating screw type minimisation rolls. The diameter of the rolls varies with different series. Available are 250 mm, 310 mm or 380 mm diameter.
The two upper rollers are pre-breakers. The third (bottom) roll works the material against the case mounted, adjustable blades.
This technique achives a steady, compost ideal sized granular spreading. The minimised and crushed fibre material is discharged in a free fall and not accelerated in any way.
The Neuenhauser screw mill reverses automatically when overloaded or non crushable material are fed into the machine and are returned into the feeding hopper.
After the pre-selected elapse of time the Neuenhauser mill continues with forward rotation. If the self protecting reverse sequence is repeated frequently within a specific period of time the mill will switch itself off entirely. A self-protection against internal damage is achieved through this advanced technique.
