Improve Your Granulator's Overall Performance and Save Money!

The condition of your grinder bed knives and rotating knives has a key performance effect on the grinder.  Having blades that are properly sharpened will increase the efficiency (cutting rate, decrease fines, decrease noise).

Almost all makes and models of blades can be resharpened at a significant cost savings over new blades. PS&E resharpens all granulator knives including bed knives, rotating fly knives, Wortex/Conair fly knives and helical knives.
