Analysis of Grinding Mill Sound Levels

这项研究的最新结果表明，噪声测量不仅可以反映产品的粒度分布，还可以反映被破碎材料的特征。因此，噪声参数可以提供与球磨机和棒磨机中研磨的大量材料中发现的不同破碎机制有关的有价值的基本信息。更好地了解这些机制将有助于制定改进的破碎模型，并提高当今研磨作业的效率。为了研究破碎机理，对各种材料进行了研究，以将颗粒破碎与整体磨机噪音水平和单个颗粒声发射联系起来。

Recent results from this study indicate that noise measurements can reflect not only the product particle size distribution but also the character of the material being broken. Hence, noise parameters could provide valuable fundamental information relating to the differing mechanisms of breakage found in the numerous materials which are ground in ball and rod mills. A better understanding of these mechanisms will assist in the formulation of improved breakage models and result in increased efficiency of present-day grinding operations. To investigate the breakage mechanisms, work is performed on a variety of materials to link particle breakage with overall mill noise levels and with individual particle acoustic emission.
