我矿二选车间石墨选矿工艺中,二次再磨机的排矿,过去一直系用原设计槽泵(7.5千瓦)将矿浆提升到二次精选,后因槽泵时常出现故障,严重影响生产正常进行。经改用2(1/2)PS砂泵(13千瓦),但仍然故障不断,不能正常安全运转,直接影响了生产,同时也影响了石墨产品质量和数量的提高。在揭批“四人帮”和工业学大庆的群众运动中,在全国科技大会精神鼓舞下,我矿技术人员为了解决上述问题,学习推广了广西大厂矿务局的经验,采用空气提升器代替了2(1/2)PS砂泵输送石墨矿浆,效果良好。从一九七七年
In the mine beneficiation workshop graphite beneficiation process, secondary re-grinding machine drainage, the past has been the Department of the original design of the tank pump (7.5 kW) to enhance the pulp to the second choice, because of frequent failure of the pump tank, a serious impact Production is normal. After the switch to 2 (1/2) PS sand pump (13 kW), it still failed continuously and could not operate normally and directly affected the production. At the same time, it also affected the quality and quantity of graphite products. Inspired by the massacre of the “gang of four” and the industrialization of Daqing, encouraged by the spirit of the National Science and Technology Conference, our mine technicians studied and popularized the experience of Guangxi Dachang Mining Bureau to replace the 2 (1/2) PS sand pump delivery of graphite pulp, the effect is good.
