摘要： A rotary pelletizing machine includes a housing and a pelletizing assembly removably secured in the housing and including a rotatable matrix disc, upper and lower punches supported in the matrix disc for joint rotation therewith and axial displacement relative thereto, upper and lower cams for controlling positions of the upper and lower discs, and elements that enable rotation of the matrix disc relative to the cams. Upon releasing elements that secure the assembly in the housing, the pelletizing assembly can be lifted from a drive shaft that extends in the housing for imparting rotation to the matrix disc, as a unit.

摘要： To monitor the pressing forces of an upper and lower piston of a tablet press which cooperate as a piston pair, in the currently-known process an average value formed from successive pressing force measurement results is compared with two adjustable tolerance bounds and that average value is correlated with two adjustable individual value limits which follow the course of this average value or are fixed. Maxima of individual pressing force measurements are compared with these individual value limits. To detect certain operational difficulties involving slight damage to an individual piston while avoiding tolerance ranges which are so narrow that frequent stopping of the press occurs piston pair average value limits, with which the piston pair average value of the pressing force is compared, are associated with the individual piston pairs. These piston pair average values are stored in a controlling computer which can stop the tablet press and indicate a faulty piston.
