Pelletizing device

Pelletizing device comprising:

• a rotary drivable at least partly cylindrical die and within that a die cavity, an axis of rotation of the die being substantially horizontal and the at least one partially cylindrical die comprising multiple radial openings for forming of pellets;
• and
• at least one roller rotatable around a stationary, essentially horizontal shaft for pressing a material to be pelletized through the multiple radial openings in the at least partially cylindrical die, wherein the at least one roller comprises at both axial ends a sealing assembly, wherein each of the at least one rollers is fixed to a corresponding stationary shaft by roller bearings, wherein the pelletizing device comprises an oil circulation system for lubricating with oil the roller bearings of the at least one roller, and wherein the oil circulation system comprises:
• an oil pump;
• an oil reservoir, connected thereto;
• a supply pipe for leading oil to each of the roller bearings;
• and
• a return pipe for returning oil from each of the roller bearings to the oil reservoir,
• wherein for each of the roller bearings, the supply pipe and the return pipe end at axially different sides of the respective bearings,
• wherein the sealing assembly at least comprises an oil seal for sealing the oil circulation system and between the oil seal and the die cavity comprises a die cavity seal is configured to prevent that the material from the die cavity getting into the oil seal.
