1970年,我们接受了本钢歪头山铁矿矿山采选工程设计。我们遵照伟大领袖毛主席关于“在实施增产节约的同时,必须注意职工的安全、健康和必不可少的福利事业;如果只注意前一方面,忘记或忽视后一方面,都是错误的”教导,决心既要搞好选厂工艺设计,又要做好车间防尘、厂区环境保护工作。在设计中,我们大胆地采用了湿式自磨工艺,代替传统的老三段破碎(三段破碎、筛分)球磨作业的工艺。这种新的工艺,除了技术经济指标比较先进之外,还比老三段破碎(三段破碎、筛分)球磨工艺减少了很多扬尘点,为搞好选矿厂的防尘工作创造了极为有利的条件。若采用传统的老三段破碎球磨工艺的流程,象本钢歪头山铁矿这样650万吨/年规模的
In 1970, we accepted the design and engineering of BenQing Waitu shan iron ore mine. We follow the example of Chairman Mao, the great leader, that "we must pay attention to the safety, health and essential welfare work of our employees while implementing the plan of saving production. If we only pay attention to the former, forgetting or neglecting the latter, it is a wrong teaching , Determined not only to make a good selection of process design, but also do a good job workshop dust, plant environmental protection. In the design, we boldly adopted the wet self-grinding process, instead of the traditional third-stage crushing (three section crushing, screening) ball milling process. This new technology, in addition to the more advanced technical and economic indicators, is also much cheaper than the third-stage crushing (three-stage crushing and screening) ball milling process, which is extremely beneficial for dust prevention in the concentrator conditions of. If the use of the traditional third-segment crushing ball milling process, like Benxi Iron Castleys Waitangshan 6.5 million tons / year scale
