Abstract

PURPOSE: To prepare a powdered quick lime at a low cost, by kneading limestone powder and coke powder with water, and calcing the resultant kneaded material in a sintering machine in preparing powdered quick lime as a raw material for a sintered ore in a blast furnace.
CONSTITUTION: In preparing a powdered quick lime as a raw material for a sintered ore used in a blast furnace, a powdered limestone (A) and powdered coke (B) are dropped from the respective hoppers 1 and 2 to a belt feeder 4 with a belt feeder 3, introduced into a mixer 5 and kneaded with an adequate amount of water (C). The resultant kneaded material is then formed into a layer of constant thickness on a pallet 9 of sintering machine through a surge hopper 6. The powdered coke in the kneaded material is then ignited by a coke gas (D) by an igniting furnace 8 while moved on the pallet 9. Air is sucked and passed from wind boxes 10 under the pallet 9, an electrostatic precipitator 13 and an exhauster 14 through the raw material layer to calcine the powdered limestone as a powdered quick lime and take out the aimed product quick lime (E).
