ABSTRACT:
A briquetting machine including a pair of compacting rolls, a pair of cheek plates enclosing the nip of the rolls, a generally rectangular feeding chute having a damper, means for automatically regulating the damper to control the roll force and a rectangular off-gas conduit extending upwardly from the nip, all designed to uniformly feed the rolls, minimizing feed entrainment in the off gas, and when hot materials are fed, to minimize exposure of the rolls to heat. Also included are cooling enclosures for the rolls and other parts exposed to high temperature and means for measuring the temperature of each roll and automatically regulating the flow of the cooling fluids and the positions of the cooling enclosures so as to maintain the temperature of the roll surfaces within predetermined ranges.
