Analysis of Grinding Mill Sound Levels

最近的研究结果表明，噪声测量不仅可以反映产品粒度分布，而且可以反映被破碎物料的特性。因此，噪声参数可以提供有价值的基本信息，这些信息与在球磨机和棒磨机中研磨的许多材料中发现的不同断裂机制有关。更好地理解这些机制将有助于制定改进的断裂模型，并提高当今磨削操作的效率。为了研究破碎机制，对各种材料进行了研究，将颗粒破碎与整个磨机噪声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.
