Ring die pellet mill machine
The answer depends on how often you use the Pellet Mill and what kind of biomass you pelletize. Constant use of 4 to 8 hours a day over a period of 6 months using sawdust will wear down the die and rollers and they may need to be replaced. Less use of course and softer biomasses like grasses, leaves, and paper goods, could mean the die and rollers last well over a year. Changing to sealed bearings in the rollers is a good idea.
