A die for a rotary compression press, comprising a die holder axially supported in a guide bore and a die insert which is seated in the end-side bore of the die holder via a trunnion-shaped projection and is adapted to be mounted via releasable fastening means, wherein the projection is helically guided in the bore between axially spaced stops and is biased by a spring towards the associated front-end face of the die holder.

Die for a rotary compression press

A rotary compression press for cylindrical compacts, especially tablets, comprising a rotatably driven rotor including a die-plate and an upper and a lower ram guide for upper and lower rams cooperating with the die bores, and a pressure station with an upper and a lower pressure roller for applying a pressing power to the rams wherein the rams circumferentially have an annular tooth system which cooperates with an opposed tooth system in the area of a pressure station for the rams for the purpose of rotating the rams in the die bores thereof, characterized in that the opposed tooth system is defined by a rotatably supported gear which is acted on by a preset braking torque with the braking torque being chosen so as to be smaller than the torque of the ram when under a maximum pressing power.

Rotary compression press

An operating stand for a tablet press device which comprises a process computer with a screen and an input keyboard and where appropriate a printer, wherein the operating lectern is mounted height-adjustable on a traversable base and between the base and the operating lectern there is arranged a linear adjusting drive with a linear guide.

Operating stand for a tablet press device

A rotary tablet press, with a die plate rotatably mounted in a housing, which comprises guides for the upper and lower punch, whose position is controlled by cam disks rigid with the housing, and with an upright drive shaft which is arranged below the die plate and which can be releasably coupled to the die plate, wherein the die plate is formed such that after releasing from the drive shaft and a slight raising it may be moved out laterally, wherein at the ends, facing one another, of the die plate and drive shaft there is provided a quick locking whose parts are arranged in cavities of the die plate and drive shaft and which may be actuated by an actuation rod which is movably mounted in an axial channel of the drive shaft and is actuatable by an actuation device for the selective tensioning or releasing of the die plate and drive shaft.

Rotary tablet press

A rotary tabletting machine with a housing, with a matrix disk in the housing, which in an upper and a lower receiving section guides the upper and lower punch, with an upper and lower cam carrier ring rotationally rigid relative to the housing, for control of the upper and lower punch and with an upright drive shaft, below the matrix disk, driven by a rotational drive and releasably connectable to the matrix disk, wherein the matrix disk and the cam carrier rings with the upper and lower punch after release from the connections as an assembly may be commonly removed from the drive shaft, whereby the cam carrier rings laterally in each case are connected to at least one arm and the arms via an upright connection section are rigidly connected to one another and the connection section is releasably couplable to the housing such that it is secured against rotation.

Rotary tabletting machine

Method and device for adjusting a stamp relative to a matrix with sinter-pressing

An apparatus and method for determining the force-displacement diagram of pairs of punches in a rotary pelleting machine involving measuring and storing the course of compression of punch pairs for each individual angle step, storing said data and preparing a correction table in a computer which is compared to the theoretical values of displacement.

Method and apparatus for determining the force-displacement diagram of

A method of depositing dosed quantities of pulverized lubricants or parting compounds on the materials contacting surfaces of pressing tools of tabletting machines, according to which the parting compound uniformly distributed by a gaseous transport medium is blown on the surfaces, said parting compound during operation of said tabletting machine being continuously blown on the used surfaces and being removed from the areas adjacent to the used surfaces by suction continuously.

Method and device for depositing pulverized lubricants or parting

A sealing strip for a housing of a pelletizing machine has a one-piece sealing body with a central web with an upper side having two upper edges and a lower side having two lower edges, two sealing lips extending from the upper edges of the upper side of the central web at an angle relative to one another, and a clamping strip extending from a center of the lower side of the central web and provided with lateral webs.

Sealing strip for housing of pelletizing machine

A rotary pelletizing machine has a rotatable matrix disc, a plurality of vertically adjustable pressing rollers which control position of the upper and lower plungers, a drive for a height adjustment of the rollers, a housing accommodating the drive, and a bearing block supporting the pressing roller and releasably connected with the housing.

Pelletizing machine

A rotary pelletizing machine comprises a rotatable matrix disc, a plurality of upper plungers and lower plungers guided in the matrix disc, and an element for holding the lower plungers from falling out during a dismounting of the matrix disc, the holding element including a braking ring arranged in the matrix disc and pressing radially against the lower plungers so as to hold the lower plungers from falling out.

Rotary pelletizing machine with matrix disc having copper and lower

A rotary pelleting machine comprises a housing, a drive shaft, a matrix disc connected with the drive shaft and guiding upper plungers and lower plungers, a unit for controlling position of the plungers during rotation of the matrix disc. The unit includes a cam ring provided for controlling the upper plungers. The cam ring is supported rotatably relative to the housing and the drive shaft. Also a unit for measuring a torque of the cam disc is provided.
