PROCESS AND APPARATUS FOR COMPRESSING, AND MONITORING THE COMPRESSION OF, PULVERULENT MATERIALS AND A PRESS APPLYING SAME

摘要

This invention relates to an apparatus for compressing and monitoring the force of compression detected by a sensor and/or the height of doses of pulverulent materials which are compacted in a container by a punch, wherein it comprises: a spindle for monitoring the force of compaction comprising: a screw-nut system driven in rotation by a driving member, a housing provided with at least one force sensor, interposed between the screw-nut system and the punch and adapted to be displaced in slide by the screw-nut system, and a circuit for servo-control of the driving member in relation with the successive measured values of the force of compaction and with a reference value of force. The invention also relates to a process for controlling the apparatus and to a press for applying same.
