摘要:
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.
摘要:
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.
