A system for recirculating lubricant to cool and lubricate a pellet mill including: a die; first and second roller assemblies received by the die; and a main shaft in communication with the roller assemblies, a pump, and a reservoir. The system provides fluid to a cavity formed between an inner surface of the plurality of bearings, an inner surface of the roller shell, a liner and a seal on each end of the roller shaft of each of the roller assemblies. Fluid fills the cavity through a first passage of the roller shaft of the roller assembly until fluid can enter a second passage of the roller shaft of the roller assembly. From the second passage, fluid may flow out of the roller shaft and roller assembly to another roller assembly or back to the main shaft.
