Developments in granulator design
Monday, 04 April 2022
- Rotor design.
Some granulator rotors have the bolts that fasten the blades, screw directly into the rotor. Should the thread be damaged it is very difficult to affix a drill onto the rotor and fit a helicoil. In addition, the heads of the bolts are in the high wear area and prove difficult to unscrew when worn.
In contrast, in the new generation granulators the fastening bolt passes through the rotor and screws into a retaining plate with the benefits:
- The bolt head is not in the wear area and is protected.
- The bolts screws into a retaining plate in top of the blade.
- Should the thread be damaged on simply make a new retaining plate.
