摘要:介绍烧结机副原料（熔剂）破碎筛分系统技术的的改造，节省投资，利用资源，满足生产而作的技改方案，并对技术上的可行性进行多种探讨。

　　　石灰石，白云石，蛇纹石及消石灰或生石灰等的来源，年供给量，运距及运输方式。各项熔剂的平均化学成分，粒度，含水量。烧损及堆积密度。

　　　熔剂是高炉冶炼过程中的造渣物质。按其性质可分为碱性熔剂、中性熔剂和酸性熔剂三类。由于我国铁矿石的脉石成分绝大多数以SiO2为主，所以通常采用含有CaO和MgO的碱性熔剂。在烧结生产中加入熔剂，不仅可改善烧结过程，强化烧结，提高烧结矿质量、品质，而且可以向高炉提供自熔性和高碱度的烧结矿。熔剂与矿石中的高熔点脉石能生成熔化温度较低的易熔体；能造成一定数量和一定物理化学性能的炉渣，达到去除有害杂质的目的（如去硫）。

ABSTRACT:The sintering machine auxiliary material (flux) transformation of crushing, screening system technology can save the investment, utilization of resources, technical solutions to meet production and made, and the feasibility of the technique on various study.

　　　 Limestone, dolomite, source of serpentine and lime or lime, year of supply, transport distance and transport. The average chemical composition, the flux of particle size, moisture content. Burning and bulk density.

    Flux is slagging material of blast furnace smelting process. By their nature can be divided into alkaline, neutral and acidic flux flux flux three. The gangue of iron ore in China the most mainly to SiO2, so we usually use basic flux containing CaO and MgO. Adding flux in sintering production, not only can improve the sintering process, sintering, improve sinter quality, quality, but also to provide self-fluxing sinter blast furnace and high alkalinity. High melting point and gangue flux in the ore can generate lower melting temperature is easy to melt; the slag can cause a certain amount and some physical and chemical properties, to remove harmful impurities (such as the purpose of desulphurization).
