A method for operating a rotary press, comprising a rotor rotatably driven about a vertical axis that has a die-plate and upper and lower rams which, while being guided vertically in guides of the rotor, interact with holes of dies in the die-plate wherein at least one compression station is provided and has an upper and a lower pressing roller past which the presser rams run along and by which they are moved towards the die-bore for the purpose of compacting the material in the die-hole, wherein the upper and lower rams are lifted subsequent to the compression procedure, causing the lower ram to eject a compact from the die and the compact to be stripped by a stripper in the direction of a discharge chute, characterized in that while an compact ejection procedure is under way the upper ram stands upright on top of the compact and is lifted therewith and the stripper seizes the compact laterally while the upper ram is still standing upright on top of the compact.

Powder press

A punch for a rotary press, which has a shaft and a head, wherein the head has an upper mirror surface, a cylinder surface and a rounded transition area between the mirror surface and cylinder surface with a first and a second radius, wherein the first radius is larger than the second radius and wherein the punch head also has a preferably conical transition area from the cylinder surface to the shaft, wherein the diameter of the head is less than 25 mm and the first radius of the transition area is selected such that its height is less than half the height of the cylinder surface.

Punch for a rotary press

A filtering plant for removing dusts from gases, with a plurality of filter units, which are parallel connected to a line for crude gas and the outlets thereof are parallel connected to a line for purified gas, wherein an extraction blowing engine is connected to the line for purified gas, further with an apparatus for cleaning the filter units, which has a lower collecting space for the filter cake with a discharge opening with flap on the lower end of the collecting space, characterized in that the dust discharge openings of all the filter units except one are connected to a common collecting main and the collecting main is connected to the crude gas region of the one filter unit.

Filtering plant for removing dusts from gases

A cooling system for a rotary tablet press with which a rotor is driven by an electrical drive motor and the rotor and drive motor are arranged in a closed housing, and a control cabinet for the drive motor and further units in the housing, wherein arranged within the housing is a cooling machine whose evaporator is part of a first heat exchanger, whose other part is arranged in a coolant circuit for the drive motor, a fan is arranged in a channel in the housing closed relative to the housing interior, where the fan draws cool air in via an air inlet of the housing and gives it off via an air outlet of the housing, wherein the cool air is engaged in heat exchange with a condenser of the cooling machine.

Cooling system for a rotary tablet press

An apparatus for the elimination of dusts from gases, with a filter arrangement, which is flown through by a loaded volume flow, and a cyclone which is arranged upstream to the filter arrangement, wherein a collector funnel below the filter arrangement forms the cover of the cyclone, wherein a branch stub forming the dust outlet opening of the collector funnel forms the dip pipe of the cyclone and an outlet opening of the cyclone is connected to a dust collector tank arranged under it.

Apparatus for the elimination of dusts from gases

Press for producing dimensionally stable pressed parts from powdered material, with a press frame, a die holding plate, at least one upper punch holding plate, at least one lower punch holding plate, adjusting drives for the upper punch and lower punch holding plate and/or die holding plate, a vertical guide in the press frame for at least the upper and lower punch holding plate and a measuring device for measuring the position of the upper punch holding plate, the lower punch holding plate and/or the die holding plate. A single measuring rule is attached in its thermal fixed reference point to a support vertically uncoupled from the press frame, on which measurement slides cooperating with the holding plates are guided.

Press

A press for the manufacture of dimensionally stable compacts from powdered material, characterized by the features of a press frame having vertically adjustable columns and cross-connections, a die retainer plate, at least one upper ram retaining plate, at least one lower ram retaining plate, a guide column outside a press main axis which has two parallel guideways on which all retainer plates are adapted to be guided vertically on one side or be selectively locatable, wherein the lower end of the guide column is fixedly coupled to a frame-mounted lower plate and the upper end is located on the press frame, an upper adjustable drive adapted to be located on the press frame, for the upper retaining plate (), a lower adjustable drive () for the lower retaining plate () and the die retainer plate, if desired, and which is fixed to the frame-mounted lower plate.

Rotary press with a rotor, rotatingly drivable around a vertical axis of rotation, which has a die plate with die bores and upper and lower punches guided in guidings, radial cams for the upper and lower punches, at least one compression station with upper and lower pressing roller, at least one filling equipment and at least one stripping device for pressed articles which are ejected from the die bores, characterized in that the rotor has an annular plane situated radially outside of the graduated circle for the die bores, which is concentric to the axis of rotation and is lowered with respect to the upper side of the die plate about a predetermined degree, first deflection portion direct the ejected pressed articles to the annular plane and second deflection portion direct the pressed articles from the annular plane towards the outside.

Rotary press

A device for the guidance of lower rams across the lower-ram head in a rotor-type rotary press in the area of a filling device wherein a charging cam is disposed between an ejector cam which precedes as viewed in the direction of production and a proportioning cam adjustable in height and is configured such as to lower the heads of the lower rams revolving along with the rotor from the level at the end of the ejector cam to a lower-located transition level of the proportioning cam, a press-mounted, first charging-cam element having a first filling-cam portion joining the ejector cam is provided on which the lower-ram heads are guided solely on the side facing the rotor axis subsequent to the ejector cam, an adjustable second charging-cam element is provided and has a second filling-cam portion on which the lower-ram heads are guided solely on the side facing away from the rotor axis before encountering the proportioning cam, that the second charging-cam element is displaceable both vertically and in the circumferential direction of the rotor for the purpose of varying the filling depth along a predetermined adjustable upward slope, and the first and second charging-cam elements have third, helically shaped filling-cam portions which are located between the first and the second charging cam portion and are located partially opposite each other, and guide the lower-ram heads jointly through a certain length, wherein the upward slope of the third filling-cam portions matches with the adjustable upward slope.
