江西第十三矿四坑选矿厂电工刘以柏,与技术人员协作,研究制成了跳汰机床底砂观测器。在生产中使用了几个月,不仅解决了床底厚度测量不准确,影响选矿回收率计算不准的老问题,而且给跳汰过程的分层研究工作提供了有利条件。过去,这个厂由于不能正确贯彻执行跳汰机的技术操作条件,跳汰机床底砂过厚或过薄,都直接影响了选矿回收率,不能正确评价各班组的生产成绩。需 Jiangxi thirteenth mine Sikeng beneficiation plant electrician Liu Yibo, in collaboration with the technical staff to study and made a jig machine bottom sand observer. Used in production for several months, not only solved the inaccurate bed thickness measurement, affecting the recovery of ore dressing calculation of the old problems, but also to the jigging process of stratification research provides favorable conditions. In the past, due to the factory can not correctly implement the technical operating conditions of the jig, jigging the bottom sand too thick or too thin, it has a direct impact on the beneficiation recovery rate, can not correctly evaluate the production performance of each team. need
