REDUCTION EQUIPMENT FOR METAL OXIDE
Document Type and Number:
Japanese Patent JP3579652
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide reduction equipment for metal oxide of a rotary furnace hearth type reduction furnace which is capable of reducing the inexpensive metal oxide by simplifying stages from dehydrating to molding in reducing power raw materials containing much moisture and to cost effectively recycle the dust and sludge generated in a stage of refining or working the metal.
SOLUTION: The reduction equipment consists of pretreatment equipment of the power raw material composed of a device for mixing the powder containing the metal oxide in a state of containing ≥100% moisture of the total of the powder mass and the powder mainly composed of carbon, a slurry transporting device, a slurry dehydrating device and a compression type molding device for manufacturing moldings and the rotary furnace hearth type reduction furnace as main equipment.
