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.

这项研究的最新结果表明，噪声测量可以 不仅反映了产品的粒度分布， 被破坏的材料的特性。 因此，噪声参数可以 提供有关不同的有价值的基本信息 在研磨的许多材料中发现的断裂机制 在球和棒米尔斯轧机中。 更好地理解这些机制将 协助制定改进的破损模型， 提高了当今研磨操作的效率。 到 研究断裂机制，工作是在各种各样的 将颗粒破碎与磨机整体噪音水平联系起来的材料， 单独的粒子声发射。
