摘　　要：以宁明膨润土矿制备有机包膜复合粘结剂,通过钠化、挤压、有机促进剂、包膜等工艺的中试研究,生产出胶质价350mL/3g,膨胀倍90mL/g,膨胀指数22mL/g,吸水率640%的高效钠基复合膨润土。在精矿粒度-200目47%,水份10%条件下,控制膨润土粘结剂用量为0.6%,所造生球各项指标达到工业生产要求。此研究方法为生产铁矿球团高效复合粘结材料提供了可靠依据。Organic coating composite binder was prepared by Ningming bentonite through the sodium reaction, extrusion, organic accelerator, organic coating and other processes of the pilot study. The product had the glial price of 350 mL/3g, expansion times 90 mL/g, swelling index 22 ml/g, 640% of the high water absorption of sodium bentonite composite. Under the -200 Mesh size in the concentrate 47% , 10% moisture conditions, bentonite binder was controled in the amount of 0. 6%, and the product reach the industrial production requirements. The methodology provided a basis for composite bonding material for the efficient production of iron ore pellets.
