复合耐磨材料在甲玛选矿厂的应用与实践

甲玛矿区地域偏远，工业基础薄弱，常用生产物资基本靠内地输入，单一材料因其作用有限，使用寿命不能有效延长，成为了制约选矿厂设备运转率提升的关键因素。为解决此问题，结合对工艺各环节物料的物理化学性质的研究和普查资料，对标国内外先进耐磨材料特性，通过对不同耐磨材料复合应用的实验，研制出一批应对选矿厂不同作业条件的复合耐磨材料。连续三年的工业生产实践，选矿厂设备运转率达95%以上，远超同行90%的平均线，由此带来的经济、生态和社会效益极其显著。 

Application and Practice of Composite Wear-Resistant Materials in Jiama Concentrator

Jiama mining area is remote and its industrial base is weak. The common production materials are imported from the mainland, and the single material cannot prolong the service life effectively because of its limited function. In order to solve this problem, based on the general survey data and the research on the material properties of each process link, the advanced properties of the wear resistant materials at home and abroad are marked, and the composite application tests of different wear resistant materials are conducted. A batch of composite wear-resistant materials have been developed to deal with the different working conditions of the concentrator. After three years of industrial production, the equipment operation rate of the concentrator reached over 95%, far exceeding the average of 90% of its peers. The resulting economic, ecological and social benefits are extremely significant.
