本文讨论了重力分选过程分配曲线的精确性,它同时受到密度分析系统分离精度和所选择的密度间隔宽度的强烈影响。当分选产品的密度分析不能采用重液而不得不采用重悬浮液或其他系统(如磁重分离)时,这个问题是严重的。这些系统的不完全分离和所采用的密度间隔只能得到分选过程的表观分配曲线,而不是实际分配曲线。本文采用模拟程序研究了不同条件下表观分配曲线和实际分配曲线的关系。一旦得到了表观分配曲线和密度截取精确度,对于不同的输入资料可得到不同的特性曲线,从而计算出实际分配曲线和相应参数。引言分配曲线的确定对控制重力分选过程具有相当大的重要性。它能提供不同粒度和密度的粒级在分选装置中的行为,从而作出适当修正以控制分选过程。另外,与特定分选过 This article discusses the accuracy of the gravity distribution process distribution curve, which is strongly influenced by both the separation accuracy of the density analysis system and the chosen density interval width. This problem is serious when the density analysis of sorted products can not use heavy fluids and has to use resuspension or other systems (such as magnetic separation). The incomplete separation of these systems and the density interval used can only give an apparent distribution curve for the sorting process, rather than the actual distribution curve. In this paper, the simulation program was used to study the relationship between the apparent distribution curve and the actual distribution curve under different conditions. Once the apparent distribution curve and the density interception accuracy are obtained, different characteristic curves can be obtained for different input data so as to calculate the actual distribution curve and the corresponding parameters. Introduction The determination of the distribution curve is of considerable importance for the control of the gravity separation process. It provides particle size and density of different particle sorting device in the behavior, and make appropriate amendments to control the sorting process. In addition, with specific sorting
