过去对球磨机滞留量的实验研究 ,是使用同位素指示器及停留时间分布分析 (RTD) ,在研究中 ,球磨机内的所有介质在实验后被称重 ,由于固定的实验设置 ,或者是在工业闭路磨机中通过RTD方法测量滞留量的难度 ,结果在滞留量测量和磨机给矿之间的相关关系不一致。在本实验中 ,仔细制定的半工业实验结果使磨机滞留量的测量能够在磨机运行中实时进行 ,因而 ,可得到极其准确的滞留量数据和瞬时滞留量数据。根据这些数据建立起滞留量作为操作条件的函数的正确趋势。本文对观察到的趋势的解释有助于说明以前发表的数据的异常情况。
In the past, experimental studies on the retention of ball mills were carried out using isotope indicators and residence time distribution analysis (RTD), in which all the media in the mill was weighed after the experiment, either due to a fixed experimental setup or an industrial closed circuit The difficulty of measuring the amount of hold-up by the RTD method in the mill resulted in inconsistent correlation between hold-up measurement and mill feed. In this experiment, a well-developed semi-industrial test result allows mill hold-up measurements to be made in real time during mill operation, thus providing extremely accurate hold-up data and instantaneous hold-up data. Based on these data, the correct trend is established for the retention as a function of operating conditions. This article explains the observed trends to help illustrate the anomalies in previously published data.
