1.各厂要有足够的原料储存场地(一次料场),其储量应不少于1个月的用量,入场原料必须按品种成分,分类堆放,不得混堆,混放,储料场是为中和料场服务的,不能把储料场当成中和料场,也不能把中和料场当作储料场,以保证中和效果. 2.原料中和混匀是烧结生产必不可少的工序,各企业必须建立配有堆料机、取料机的机械化中和料场,进行烧结原料(粉矿、精矿等粉状铁料)的中和作业. 3.针对地方厂矿石来源矿点多、批量少、品种杂的特点,中和混匀作业前应进行预配料,以缩小品位波动.预配料系统的能力应根据所用矿种多少来确定.
1. The factory should have enough raw materials storage site (a yard), its reserves should not be less than 1 month’s dosage, the admission of raw materials must be species composition, stacking, not mixed reactor, mixed storage, storage yard Is to serve and in the yard, can not be the stockyard as a neutral yard, can not be neutralized yard as a storage yard, in order to ensure the neutralization effect. Indispensable processes, all enterprises must establish a mechanized and stocking yard equipped with stockers and reclaimers for the neutralization of raw materials for sintering (such as powdered iron ore, concentrate, etc.) 3. For local factories Ore sources mine more, less volume, the characteristics of miscellaneous varieties, mixing and pre-mixing operations should be carried out in order to reduce the grade fluctuations. The ability of pre-dosing system should be based on the number of minerals used to determine.
