Abstract
PURPOSE: To recover Zn of high content in manufacture of reduced pellets, by operating under specific conditions two dust collectors, which are installed in an apparatus capable of producing oxidized or reduced pellets at need.
CONSTITUTION: Raw pellets charged by a feeding device 2 are conveyed by a conveyer 3, passing through a grate 1 consisting of a drying chamber 4, water- removing chamber 5, a preheating chamber 6, to a rotary kiln 7. The kiln 7 is capable of producing oxidized pellets or reduced pellets by calcination in oxidizing or reducing atmosphere. Two electric precipitators or bag filters (e.g., electric precipitators 17, 18) are installed, one precipitator 17 of which is connected to a drying chamber 4. The other precipitator 18 is connected to the drying chmber 4 and to the preheating chamber 6 so as to be changed freely. At the time of production of oxidized pellets, both dust collectors 17, 18 are connected to the drying chmber 4, on the contrary at the time of production of reduced pellets, one dust collector 17 is left as it is, and the dust collector 18 is changed so as to be connected to the preheating chamber 6.
