YMT-75型大块跳汰机是一种新型的弱磁性铁矿块矿预选理想设备。1986年4月由马鞍山矿山研究院和酒泉钢铁公司签订合同共同研制。1987年4月,该院试制样机1台,同年5月到11月在酒钢选矿厂完成了工业试验,处理矿石量6000多吨,运转2000多小时,并经过72小时的稳定试验,取得了较好的试验指标:一次粗选预选75～15mm块矿,当处理能力为42.88t/h、原矿铁品位32.05％时,可抛除产率14.61％,品位16.99％的废石,获得产率
YMT-75-type large jig is a new type of weak magnetic iron ore ore pre-selected ideal equipment. April 1986 by the Maanshan Institute of Mining and Jiuquan Iron and Steel signed a contract jointly developed. April 1987, the hospital trial prototype 1 Taiwan, the same year from May to November at the Jiugang concentrator completed an industrial test, handling more than 6,000 tons of ore, more than 2000 hours of operation, and after 72 hours of stability test, made Better test index: a rough selection of pre-selected 75 ~ 15mm lump ore, when the processing capacity of 42.88t / h, 32.05% of the original iron grade, you can get rid of the yield of 14.61%, 16.99% grade waste rock to obtain the yield
