Abstract:
1. 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 essentially 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 and the oil circulation system comprises 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 at least one roller is fixed to a corresponding stationary shaft by the roller bearings, wherein the pelletizing device comprises an oil circulation system for lubricating with oil each of the roller bearings of the at least one roller, and wherein, a roller is mounted on the stationary shaft by two respective roller bearings, wherein the supply pipe ends between both such roller bearings and the return pipe ends at axial external sides of the 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 to prevent that material from the die cavity getting into the oil seal.
