A recently granted patent (Publication Number: US11878930B2) discloses a method for supplying pre-heated particulate mineral material from a separating cyclone to an inlet of a cyclone furnace. The method involves utilizing a material receiving conduit, an inclined elongated housing, and an outlet conduit to facilitate the transfer of the pre-heated material. The inclined elongated housing allows for the fluidization and controlled flow of the particulate mineral material from the separating cyclone to the cyclone furnace inlet. By maintaining a constant fluidized state and pressure differential between the conduits, the method ensures the prevention of backflow, thus optimizing the supply process.

Furthermore, the patent includes additional claims related to the arrangement and operation of the material receiving conduit, outlet conduit, and inclined elongated housing. These claims detail the provision of air inlets for fluidization, the use of a screw conveyor for further stirring and control of material flow, and specific inclinations for the housing. The method described in the patent aims to improve the efficiency and effectiveness of supplying pre-heated particulate mineral material for the production of mineral melt in a cyclone furnace. By incorporating these innovative features and mechanisms, the patent offers a comprehensive solution for enhancing the mineral material supply process in industrial settings.
