A roll assembly temperature sensing system for a pellet mill includes: a thermal sensor (160); and a pellet mill roll assembly rotatably disposed in a rotor assembly. The pellet mill roll (140) assembly includes: a roll shaft; a bearing disposed circumferentially around the roll shaft; and a seal (150) disposed between an end of the bearing and the rotor assembly. The rotor assembly includes an area defining a die cavity adjacent to the seal (150). The thermal sensor (160) is disposed within the die cavity, and is configured to detect a temperature of the seal resulting from heat conducted from the bearing.

A pellet press having a motor with a motor housing and a rotor arranged rotatably in the housing. The rotor is a hollow shaft. A pressing mechanism has a pressing mold and pressing rolls arranged in the pressing mold. The rolls are fastened to a stationary shaft. The stationary shaft is arranged in the rotor designed as the hollow shaft. A mold holder is operationally connected to the pressing mold. The mold holder and the rotor are connected to each other by a shaft-hub connection such that a transmission of a torque of the rotor to the mold holder is ensured.

A device for producing pellets has a machine frame, a hollow outer cylinder mounted therein with a first axis of rotation and an inner cylinder, arranged in the outer cylinder, with a second axis of rotation, wherein a wedge-shaped gap is formed between an inner surface of the outer cylinder and an outer surface of the inner cylinder, the outer cylinder and/or the inner cylinder has radial holes for pressing through material, and a pivot arm is arranged on each of the two sides next to the inner cylinder, on which pivot arms the inner cylinder is rotatably mounted. Each pivot arm is moveably mounted on the machine frame in the region of both ends of the pivot arm.

A pelleting device, designed as a field-guided stalk-crop harvesting machine for connection to a tractor and a chopper, wherein a diesel engine drives a current generator and an annular die press, configured such that chopped stalk material passes into a drying chamber and is propelled via a screw conveyor into the die press, wherein the annular die of the die press is mounted in ring bearings on a base, on which a pair of pivot levers for a pan grinder roller is also hinged.

A hydraulic pelletizer for pelletizing a material comprising at least one pelleting chamber consisting of at least one feed cone receiving a material, at least one die, at least one roller pressingly engaging the die, a die engagement interface, and at least one feed deflector forcing the material between the roller and the die, at least one hydraulic drive system having at least one hydraulic motor, at least one hydraulic pump, a hydraulic motor interface rotationally driving the die engagement interface, and a fluid tank; and a system controller, whereby the material enters the pelleting chamber where the hydraulic drive system powers the pelleting chamber components forming the material into a predetermined shape form in the die and upon reaching a desired size ejecting the pellets from the die.

Disclosed is a pelleting device which is designed as a field-guided stalk-crop harvesting machine and, when connected to a tractor with a chopper, includes a diesel engine that drives a current generator and also an annular die press. The chopped stalk material passes into a dry chamber and via a screw conveyor into the annular die press. The annular die of the annular die press is mounted in ring bearings on a base, on which a pair of pivot levers for a pan grinder roller is also hinged. An electric drive motor fed by the current generator drives the screw conveyor by a controller, and servomotors, which engage on the pivot levers, regulate the roller gap. The controller is governed as a function of the injection requirement of the diesel engine and/or the pressure applied by the press.

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.

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.
