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.

In a first aspect the present invention relates to a pellet mill (10) comprising a die (30) having a first surface (34) and a second surface (36), the die further comprising press holes (38) extending from the first surface to the second surface, at least one roller (50) configured to roll over the first surface for forcing a pelletizable material, forming a feed layer (2) on the first surface, through the press holes to the second surface, and a nozzle (82) configured to provide an additive fluid (4) directly into the nip (86) between the at least one roller and the first surface. In a second aspect the present invention relates to a method of producing pellets, and in a third aspect the present invention related to method of retrofitting a pellet mill.

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.

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.
