Document Type and Number:
Japanese Patent JP5571345
Kind Code:
B2
Abstract:
Disclosed is a method for producing briquettes, by which briquettes having enhanced strength can be produced even when the amount of a binder used therefor is reduced as much as possible. Specifically disclosed is a method for producing briquettes, which comprises: a step of forming a primary granular material having an apparent density of 1,000 to 4,000 kg/m 3 using a powder of metal oxides including iron oxide and one or more oxides selected from among of zinc oxide, lead oxide, and titanium oxide; and a step of forming a secondary granular material by compressing a plurality of primary granular materials, while having the primary granular materials contain one or more metal oxides selected from among the zinc oxide, lead oxide, and titanium oxide.
