摘要
分析了金口岭铜矿碎矿工艺存在的流程不合理、设备负荷不均、无法满足球磨工艺要求等主要问题。提出了解决问题的四种方案 ,并阐明了作者对改造所持的观点 ,即将现有PYD2 10 0弹簧圆锥破碎机改为单缸液压短头圆锥破碎机 (PYY16 5 0 /10 0型 ) ,同时振动筛筛孔尺寸分别为 2 2mm和 16mm ,处理铜矿石用 2台筛子 ,处理转炉渣用 1台筛子 ,从而保证两种矿石的不同产品的粒度要求。改造实施后可提高生产效率 2 8%以上 ,每年可创效益 6 0万元以上。
The main problems existed in the crushing process of Jinkouling Copper Mine,such as improper flowsheet and uneven equipment loads,are studied in detail.Four improvement proposals and the viewpoint presented by author are discussed.The existed spring cone crusher(PYD2100 type)is replaced with single-cylinder short-head crusher(PYY1650/100 type)with vibration screen sizes of 22 and 16mm respectively.Two screens are used for treatment of copper ore while one screen for converter residue,ensuring grain size of different products from two kinds of ore.After improving,productivity will be increased by 28% and the benefit of 600000 Yuan obtained yearly.
