成庄矿洗选厂设计处理能力400万t/a,随着煤炭市场需求的变化,矿井提升能力不断提高,原破碎系统能力不足,处理量低,产品粒度不能满足市场要求,极大地制约了洗选厂整个系统的正常生产和系统的提升能力。针对原破碎系统工艺复杂落后、产品粒度低、能力严重不足的状况,洗选厂经认真的市场调研,引进了MMD破碎机作为洗选破碎系统的关键环 With the design and processing capacity of 4 million t / a in Chengzhuang Coal Preparation Plant, with the change of coal market demand, the mine upgrading ability is continuously improved. The capacity of the original crushing system is insufficient, the throughput is low, and the product granularity can not meet the market requirements, greatly restricting Washing plant the entire system of normal production and system upgrade capability. In view of the complicated and backward process of the original broken system, the low particle size and the serious shortage of capacity, the washing plant has made serious market research and introduced the MMD crusher as the key ring of the washing and crushing system
