Title:
METHOD AND DEVICE FOR CHARGING SINTERING MACHINE WITH RAW MATERIAL
Document Type and Number:
WIPO Patent Application WO/2010/073968
Kind Code:
A1
Abstract:
A method of charging a sintering machine with a raw material is provided, the method being effective in inhibiting an "avalanche phenomenon" or an "undercharge phenomenon" from occurring even when the raw material to be sintered has changed in particle size distribution. The method enables stable size segregation of the raw material to be sintered. A raw material to be sintered (8) is fed to the upper end of a slit chute (1) disposed obliquely. Coarse particles (4) are allowed to slip down to a transfer wagon (9) from the lower end of the chute (1), and fine particles (3) which have passed through the slit chute (1) are allowed to slip down to the transfer wagon (9) through a deflector chute (2) obliquely disposed under the slit chute (1). The sintering machine is thereby charged with the raw material. The level of the fine particles (3) accumulated on the deflector chute (2) is always monitored, and the position of the deflector chute (2) relative to the slit chute (1) is regulated so as to keep a proper level. Namely, when the level of the fine particles (3) fluctuates, the deflector chute (2) is brought farther from the slit chute (1). When the level is stable in a position lower than the proper level, the deflector chute (2) is brought near thereto.
