自热熔练工艺对干铜精矿原料的需求,日益严格的环保法规以及减小熔炼操作成本的需求,共同促成了蒸气间接烘干技术的商业化。与传统方法相比,该技术性价比高,污染小。Kvaerner Eureka公司的铜精矿蒸气烘干机是一项已经过验证的技术,可以减少废气中夹带的粉尘,从而简化粉尘分离系统。基于Kvaerner Eureka在处理各种铜粉与其他类型粉末方面的长期经验,以及对于蒸气烘干操作中所遇问题的成因而非表面症状的透彻分析,本文将讨论使用本公司独特盘管式设计的蒸气烘干机所能带来的优势与可能发生的问题,并给出间接烘干技术评估与选择的最佳标准。
The demand for raw materials for dry copper concentrates, the increasingly stringent environmental regulations and the need to reduce the cost of smelting operations, have led to the commercialization of indirect steam drying technology. Compared with the traditional method, the technology cost-effective, low pollution. Kvaerner Eureka’s copper concentrate steam dryer is a proven technology that simplifies the dust separation system by reducing the entrainment of dust in the exhaust gases. Based on Kvaerner Eureka’s long experience in handling various types of copper powders and other types of powders, as well as a thorough analysis of the causes of problems encountered in steam drying operations rather than the appearance of surface symptoms, this article will discuss the use of our unique coil design Steam dryer can bring the advantages and possible problems, and gives indirect drying technology evaluation and selection of the best standards.
