| 摘 要： | 大冶铁矿球团厂针对铁精矿烘干系统原燃气供热回转烘干机运行成本高、抢修任务重、质量波动大等弊端，通过采用燃烧焦炭粉的高温烟气沸腾炉作供热设备、增加引风收尘系统、提高烘干机转速、采用组合扬料技术等措施进行改造，使烘干机产量由改造前的不足110t／h增加到140t／h，烘干每吨铁精矿的燃料成本由改造前的5．94元降到2．56元，实现了节能增产，很好地满足了大型工业回转干燥系统长期连续运行的需要。

| Abstract: | To traditional turn-type driers with gas-burner as heat-generator, there are of much insufficiency such as high cost-consuming?so much and usual maintenance and repair?much water in products than allowed level. In order to solve the problems mentioned above, hereby, in Daye Iron Mine Pelletizing Plant, a fluidized-bed furnace burning coke powder was used as a new heat-generator to supply the drier, the turn velocity of drier was increased, the main dry product yield has reached to 140t/h from previous 110?t/h and below, the cost of coke-consuming has decreased to 2.56 yuan RMB/t from previous 5.94 yuan RMB/t. and the quality of iron ore concentrates dried full meet the need of pelletizing production. |
