Abstract (en)
[origin: EP0365447A1] Presses for powdery materials. <??>The apparatus for compressing and controlling the compaction force is characterised in that it comprises: <??>a spindle (24) for control of the compaction force comprising: <??>a screw/nut system (28) driven in rotation by a motive unit (29), <??>a case (43) provided with a force sensor (46), interposed between the screw/nut system and the stamp, <??>and a circuit (25) for automatic control of the motive unit in relation to the successive measured values of the compaction force and to the reference force value. <??>Application to the control of the compression of powdery materials. <IMAGE>
