光电选矿是基于矿石颜色的差别而实现分选的。1970年以来,一些矿山应用这一方法代替部分手选作业,取得了一定的成效,但也存在一些问题,需要改进和提高,本文特提出几点改进措施。一、光电选矿探头现在,有的矿山已经使用2CR 型硅光电池作为信号转换器件,代替性能不够稳定的光导管,并以球面透镜聚光,效果尚好。但这种探头有横向视野窄的缺点,不能满足生产的需要。为此,建议把球面透镜改为有机 Photoelectric beneficiation is based on the difference between the color of ore and achieve sorting. Since 1970, some mines have used this method instead of some hand-picking operations and achieved some success. However, there are some problems that need to be improved and improved. In this paper, some improvements are put forward. First, photoelectric dressing probe Now, some mines have been using 2CR silicon cells as a signal conversion device, instead of performance is not stable enough light pipe, and the spherical lens condenser, the effect is still good. However, this probe has the shortcomings of narrow horizontal field of vision, can not meet the production needs. To this end, the proposed spherical lens to organic
