陕西省勉县某区办20t/d炭浆提金厂,自1987年1月试车调试以来,由于原设计采用“一段一闭路”磨矿流程,分级溢流拉度和浓度均达不到炭浆工艺要求,不能正常生产。为此,笔者建议该厂改为“一段二闭路”磨矿流程(见图1),并增设一台倾斜板浓密箱,成功的解决了长期存在的问题,取得一次试车成功和比较好的技术指标。 Mianxian County, Shaanxi Province, a 20t / d carbon slurry to pick up the plant, commissioned since January 1987 commissioning, the original design of the “one section of a closed circuit” grinding process, grading overflow pull and concentration are less than charcoal Pulp process requirements, can not be normal production. To this end, I suggest that the plant be changed to “a section of two closed-circuit” grinding process (see Figure 1), and the addition of a tilt plate thick box, the successful solution to the long-standing problems, to obtain a test success and better technology index.
