我厂的磨浮工艺为两段磨矿两段浮选;第二段磨矿细度为-0.074毫米92％以上。实践表明金浮选回收率是随磨矿细度的提高而提高的。而影响磨矿细度进一步提高的重要因素是分级设备分级效率低,粗细分不开;因此不断探索和研制高效率的联合分级方案,是提高我厂磨矿细度乃致回收率的重要途径。 原第二段磨矿是采用斜板分级箱与螺旋分级机组成联合分级。但因斜板分级箱易堵,堵后不管你是将箱内矿砂放掉还是任其堵着,最后均导致金属流失。因此我们改用旋流器与螺旋分级机组成联合
I plant grinding and floating process for the two sections of two flotation mill; grinding fineness of the second paragraph of -0.074 mm above 92%. Practice shows that gold flotation recovery rate is increased with the improvement of grinding fineness. The important factor that affects the further improvement of the fineness of grinding is that the grading equipment has low classification efficiency and can not be separated from each other. Therefore, continuous exploration and development of a highly efficient joint classification scheme is an important way to improve the fineness of grinding in our plant. . The second paragraph of the original mill is used inclined plate grading box and spiral classifier combined classification. However, due to the inclined plate ramp box easy to block, whether you are blocking the block after the ore let go of the box or let it be blocked, and ultimately lead to the loss of metal. Therefore, we use a combination of cyclone and spiral classifier
