ABSTRACT This paper discusses the incremental development of an empirical model of volumetric hold-up of slurry inside a cylindrical mill as a function of pool volume. Relevant experimental data from three geometrically similar mills were considered for calibration and testing against the pool-based model. The data included information on ball filling, slurry hold-up, mill speed, mill internal volume, shoulder, and toe angles of the media charge, as well as slurry pool angle. Initial results showed that the proposed empirical model fitted well the data not only from the three mills but also from an independent source. The one-parameter model also proved to be capable of estimating the volumetric slurry hold-up of a cylindrical mill from its load behavior to within 9% average error. Further refinement is to follow for the model to be useful over a wide range of operating conditions.

圆柱球磨机体积泥浆滞留量的基于池的模型

摘要 本文讨论了圆柱形磨机内泥浆体积滞留率经验模型的渐进式发展，该模型是池体积的函数。考虑了来自三个几何相似工厂的相关实验数据，用于针对基于池的模型进行校准和测试。数据包括有关球填充、浆料滞留量、磨机速度、磨机内部体积、介质装料的肩部和趾角以及浆料池角度的信息。初步结果表明，所提出的经验模型不仅适用于来自三个工厂而且来自独立来源的数据。单参数模型也被证明能够估计圆柱形磨机的体积泥浆滞留量，从其负载行为到 9% 的平均误差以内。
