二氧化锰矿磨粉及还原焙烧工艺设计
|
摘要
介绍了以二氧化锰矿为原料,采用单筒干燥机、高压辊磨机、电热回转窑对矿石进行干燥、磨粉、还原焙烧制备一氧化锰焙砂的生产工艺,锰还原率可达到98.5%,并可为后续浸出化合、净化、电解、后处理、蒸发结晶等工序生产电解二氧化锰及高纯硫酸锰产品提供优质原料。
The production process of manganese monoxide roasted product prepared by using manganese dioxide ore as raw material,and using single cylinder dryer for drying ore,high pressure grinding roller for milling and electrothermal rotary kiln for reduction roasting was introduced.The reduction rate of manganese can reach 98.5%,and high quality raw materials can be provided for the subsequent leaching,purification,electrolysis,reprocessing,evaporation crystallization and other process steps to produce electrolytic manganese dioxide and high purity manganese sulfate products.
