Summary

The NBS is suitable for shredding relatively soft agglomerates that may have been developed during drying, filtration process and/or from storing the material within a hopper or Silo. Products with particle sizes from a few mm to sub mm can be produced and easily controlled by simply switching the screen. The NBS is designed in a manner that allows the screen to be easily exchanged, as well as for easy cleaning and maintenance inspection. (Refer to Fig. Nibbler NBS 300/450)

Principle

Once the raw material enters the NBS, shredding and cutting forces are provided to it between the slowly rotating rotor and screen. Materials that are shredded and that pass through the screen are then collected as products. The rotors are set with beaters as seen in Fig.1. The position of the beaters can be changed to adjust the clearance between the beater and the screen. As seen in Fig.2, the interior of the screen is mountain-shaped which allows for cutting force to be applied to the raw material to help the shredding process. The size of the shredded product is adjusted by the screen’s aperture.
