1 序言分配率曲线(特兰普曲线)原来是为评价选煤指标而研究出来的,对选矿技术的发展有显著的影响。以后这一原理又被用来表示分级或磁选等方法的分离指标上,特别是随着湿式旋流器的发明,分级中的分配率曲线更经常用。但是关于分级的分配率曲线多半是用在实验过程中和研究中,据说还未能像选煤那样广泛地用于现场。一般要描绘分配率曲线是相当麻烦的,特别是在分级时,要画出正确的分配率曲
1 Preface The distribution rate curve (Tramp curve) was originally developed for the evaluation of coal preparation and has a significant impact on the development of beneficiation technology. This principle has since been used to indicate separation metrics such as grading or magnetic separation, especially with the invention of wet cyclones, where fractional distribution curves are more often used. However, the fractional distribution curve is mostly used in experimental processes and studies and is said to have not been applied to the site as widely as coal preparation. In general, it is troublesome to describe the distribution rate curve, especially when grading, to draw the correct distribution rate of curvature
