ABSTRACT:
A granulating apparatus comprising a device which adds a binder of an epoxy resin or the like into a powder to-be-treated, a screw feeder which conveys the powder to-be-treated containing the binder, and rolls which compression-molds it. By rotating the screw feeder and the rolls, the powder to-be-treated is caused to induce internal friction and to generate heat, thereby to temporarily dissolve the binder, whereupon the powder to-be-treated is pelletized. In order to temporarily dissolve the binder, the granulating apparatus is equipped with a device for measuring the temperature of the powder to-be-treated, and a controller for controlling the stirring speed of the screw feeder and the molding speed of the rolls on the basis of the measured value so as to establish a desired temperature.
