Abstract:
An apparatus for producing pellets from bulk material, in particular soft bulk material provided with meltable fractions, for example waste, plastics material or household refuse. The apparatus includes an annular die in which there are radially oriented pressing channels that extend from an inner surface of the annular die to an outer surface of the annular die. The annular die has a horizontal rotation axis passing through the midpoint thereof and is configured to be drivable in a rotation direction by a drive unit, and the annular die bounds a compression chamber, and has at least one working koller wheel, arranged in the compression chamber, for compressing and pressing the bulk material to be pelletized into the pressing channels. The apparatus can have a first and a second machine body, with the two machine bodies separable in the direction of the horizontal rotation axis of the annular die. The annular die is mounted in the first machine body and the at least one working koller wheel is mounted in the second machine body.
Abstract:
A pelletizing device comprising a rotary drivable at least partly cylindrical die, wherein the cylindrical part comprises a multitude of radial openings for forming of pellets and at least one roller rotatable around a stationary shaft, for pressing of material to be pelletized through the radial openings in the die, wherein the roller is mounted to the corresponding stationary shaft by means of at least one roller bearing and wherein the pelletizing device comprises an oil circulation system for lubricating each of the roller bearings of each of the rollers with oil.
Abstract:
An apparatus and method for the granulation of radioactive waste in which a preprocessing method for the vitrification of radioactive waste is simplified to conform to onsite conditions of a nuclear power plant, additives are improved, and pellets suitable for vitrification are manufactured. The apparatus for the granulation of radioactive waste includes: a body frame having an inlet and an outlet; a hopper supplying the radioactive waste to be transferred and fed through the inlet; a feeder transferring/supplying the radioactive waste supplied to a specific position and in a certain quantity; a stirrer pulverizing/mixing lumps of the radioactive waste supplied; an additive supply part supplying a lubricant to the radioactive waste fed into the stirrer; and a pellet press pressing the radioactive waste fed through the feeder into a pellet shape and discharging the pellet through the outlet.
