球团原料混合均匀度的快速检测方法

针对球团工艺中原料混合均匀度的快速检测问题，以变异系数CV（%）来评估各组分的均匀程度，试验测定了精矿粉与膨润土不同配比情况下球团原料的混合效果，分析了质量指标变异系数、湿度指标变异系数、元素质量分数指标变异系数3种快速检测方法的可行性，并对现场取样的球团原料进行混匀度检测，验证了前述快速检测方法的有效性，提出评判球团原料混合均匀度的标准。所得结果可为今后研究球团原料混匀度的在线检测技术提供指导。

Rapid detection method of pellet raw material mixing uniformity

Aiming at the problem of the rapid detection for raw material mixing uniformity under the pellet process, the coefficient of variation (CV) was proposed to assess the degree of uniformity of the components. And then, the material mixing effect of the concentrate powder and the bentonite under the condition of different ratio were measured in the experiment, the feasibility of the three rapid detection methods were analysed, which are the quality index CV, the humidity index CV and the element content index CV. What’s more, the pellet raw material of field sampling was tested, which verify the validity of the aforementioned rapid detection method, the standard to judge pellet raw material mixing uniformity was proposed. The obtained results can provide guidance for future research on pellet raw material mixing uniformity of online detection technology.
