鸡西市选煤厂在生产同时对重介工艺系统进行了扩产改造 ,即增设大型旋流器和精煤脱介分级筛 ,介质流程技术改造。改造后工艺系统不仅灵活 ,适应生产不同质量要求的精煤 ,而且扩大入洗量 ,经济效益显著。介耗由原来的 4 5kg/t降至 2 0kg/t,重选综合效率提高 14 5 0 %。
Jixi Coal Preparation Plant at the same time in the production of heavy media technology system for expansion transformation, that is, an additional large cyclone and coal de-classification sieve, medium flow technology transformation. After the transformation process system is not only flexible to adapt to the production of different quality requirements of clean coal, but also to expand into the wash volume, significant economic benefits. The medium consumption is reduced from 45kg / t to 20kg / t, and the comprehensive efficiency of re-election is increased by 145.0%.
