Dispersing machine

Abstract

A dispersing machine 1 comprises a fixed vessel 3, an agitator shaft 5 rotating at a high speed in the fixed vessel, agitating pins 7 provided to project on an outer circumferential surface of the agitator shaft and an inner circumferential surface of the fixed vessel, and balls B loaded in the fixed vessel in advance, whereby materials supplied into the fixed vessel so as to be treated are dispersed and mixed by agitation by means of the balls and the agitating pins, wherein each of the agitating pins 7 includes a stud bolt 42 and a pin body 44 which is made of a sintered hard alloy shaped into a capitate cylinder, dispersed so as to cover the stud bolt, and fixed to the stud bolt by soldering, pin fitting holes 51 are formed through a wall portion of the fixed vessel so that skirt portions 45 of the respective pin bodies of the agitating pins are fitted into the pin fitting holes, and box nut members 30 are fixed to an outer circumferential surface of the wall portion in positions corresponding to the pin fitting holes so that the stud bolts are screwed down to the nuts, and at least the agitating pins provided to project on the inner circumferential surface of the fixed vessel are attached so that skirt portions of the respective pin bodies of the pins are buried in the pin fitting holes.
