ABSTRACT:
An arrangement for controlling the temperature of an arbor-sleeve type roll employed in a rolling process such as in a briquetting machine by transporting temperature control medium to the extremities of the working surface of a removable sleeve by providing in the arbor a system of passageways extending radially and terminating at a point beneath the outer surface of the arbor and by providing in the sleeve a system of interconnecting axially extending passageways. Both of these systems are joined by manifold ring assemblies mounted externally of the roll and which include an expandable bellows which compensate for thermal variation of the roll during the briquetting process. Two other rings, also mounted externally, are connected to the opposite sides of the arbor and sleeve, thereby preventing relative movement between the arbor and sleeve and still permitting the quick removal and replacement of the sleeve.
