为了提高烧结矿质量，解决细精矿烧结料层透气性问题，采用了千分之几的Ｈ粘结剂，以强化细精矿混合料的制粒效率，提高制粒小球的冷、热态强度。本文着重进行了制粒研究，并进行了制粒扩大试验和烧结对比试验。在技术经济上均取得了良好的效果，为细精矿烧结开辟了高产、优质的途径
In order to improve the quality of sinter, to solve the gas permeability of fine ore sinter material layer, using a few thousandths of H binder, to strengthen the granulation efficiency of the fine concentrate mixture, pelletizing pellets to improve the cold and hot State strength. This article focuses on the granulation research, and conducted a granulation expansion test and sintering contrast test. In the technical and economic have achieved good results, fine-grain sinter has opened up a high-yield, high-quality way
