Title:
METHOD FOR PRODUCING STARTING MATERIAL FOR SINTERING
Document Type and Number:
WIPO Patent Application WO/2011/004907
Kind Code:
A1
Abstract:
Disclosed is a method for producing a starting material for sintering that allows for the efficient production of an excellent starting material even when using a disk pelletizer for pelletization. Sintering starting materials, other than the limestone-based and the solid fuel-based powder starting materials, are load into a drum mixer (1) for mixing and stirring, where said powder starting materials are mixed, and the resulting mixture is supplied to a disk pelletizer (2) and pelletized. The pellets obtained by pelletization are supplied along with the limestone-based powder starting material to a drum mixer (3) for outer layer formation. Then, the solid fuel-based powder starting material is added so that by the time that the pellets reach the discharge port of the drum mixer (3) for outer layer formation, a limestone-based powder starting material layer and a solid fuel-based powder starting material layer have formed by adhesion to the outer layer of the pellets. In this manner, in the adhering of the solid fuel-based powder starting material to the outermost layer of the pellets for sintering, which have been pelletized by the disc pelletizer (2), making it possible to reliably avoid uneven burning during sintering.
