ROTATING FURNACE FOR HEAT TREATMENT OF LUMP-FORMING PRODUCT Russian patent published in 2010 - IPC F27B7/10 

FIELD: machine building.

SUBSTANCE: furnace consists of inclined cylinder case equipped inside with perforated drum, of milling components, of a loading device and of branches for gaseous and solid products output. The drum is made in form of a truncated cone; the loading device is located on the side of a smaller base of the cone; also perforation of the drum is made on a part of the cone surface adjacent to the bigger base; angle of semi-opening of the cone is bigger, than maximal angle of incline of the furnace case; notably, the case of the furnace is tilted to a loading side.

EFFECT: facilitating complete control over all parametres of process, considerable reduction of production premises area occupied with installation and simplification of furnace maintenance on a whole due to reduced number of internal units of structure.
