Title:
METHOD AND APPARATUS FOR PRODUCING BRIQUETTE FOR METAL RAW MATERIAL
Document Type and Number:
WIPO Patent Application WO/2006/035818
Kind Code:
A1
Abstract:
A method for producing a briquette for use as a metal raw material , which comprises subjecting a material containing a metal powder for recycling to compression molding to prepare a porous material, and charging the resultant porous material into a tubular member and blowing a hot air into the tubular member, to thereby dry the porous material. The above method improves the drying efficiency for the porous material, and simplifies the constitution of an apparatus to be used and allows the reduction of the area required for the installment of the apparatus, while shortening the time for drying, which results in allowing the lowering of the running and initial costs for the production of a briquette.
