| 摘 要： | 通过对旋流器结构参数的分析研究,探讨了旋流器锥角、给矿段材质、溢流管和沉砂嘴直径、溢流管长度对铅锌矿尾砂分级沉砂产率的影响,试验给出了不同旋流器锥角、给矿段材质和溢流管长度下的沉砂产率的变化情况。结果表明:在本试验范围内,给矿浓度为21%的条件下,10°单锥旋流器对尾砂分级沉砂产率的影响最大,且Si C材质给矿段较不容易被磨损并对旋流器的沉砂产率有较为明显的影响,当溢流管直径20 mm,沉砂嘴直径48 mm,溢流管长度为285 mm时,旋流器分级沉砂产率最高值可达49.37%。本试验对提高旋流器分级沉砂产率、改善矿山采充失调等具有一定的参考价值。

| Abstract: | Through the analysis of the optimal structural parameters of the hydrocyclone, the effects of the cone angle, the feed section material, the diameters of the overflow pipe and grit mouth, and the length of the overflow pipe on the graded yield of the tailings of the lead and zinc ore are discussed. The results show the change of the grit rate under different cone angle, feed section material, and length of overflow pipe. The results show that the 10 degrees single cone hydrocyclone has the greatest influence on the graded yield of tailings, and the SiC material is less likely to be worn out under the condition of 21% feed concentration. And the graded sedimentation rate of the cyclone is more obviously affected. When the diameter of the overflow pipe is 20mm and the diameter of the grit mouth is 48mm, the length of the overflow pipe is 285mm, the highest rate of cyclone grading is up to 49.37%. This test has some reference value for improving the hydrocyclone grading and the mining efficiency of mine. |
