PRODUCTION OF NON-BURNING AGGLOMERATE

PURPOSE:To efficiently produce non-burning agglomerate having excellent strength with good efficiency at a low cost by adding a specific amt. of molasses to sintering returns, sintering minus sieve ore, dust, etc., humidifying and kneading the mixture, then curing the mixture for a prescribed time at room temp. and molding the mixture. CONSTITUTION:The sintering returns or the sintering minus sieve ore and the dust of the powder finer than these powders are fed out of respective compounding vessels 31 to 33, are mixed by mixers 34, 35 and are humidified at need. The resulted powder mixture is charged together with the generated power via an accepting and compounding vessel 36 into a mixing machine 37 where 1 to 6wt.% molasses or the dilute liquid thereof is incorporated as a binder to the mixture and the powder mixture is kneaded to humidify the raw material mixture to a total water content of about 1.5 to 4.5%. The raw material mixture is then rested and is cured for the prescribed time at room temp. The curing time is preferably at least >=1 hours and is preferably confined within about 24 hours. The raw material mixture is thereafter supplied via a kneader 39 to a molding machine 40 and is agglomerated to
