基于剪切体积功率的概念，开发了搅拌磨模型，并将其应用于矿物加工系统中常见的几何形状。推广这个模型允许其用于模拟更复杂的轧机几何形状，如那些描述锥形盘磨机和钴磨机。由于剪切-体积功率的可加性，可以通过几何分解来计算复杂米尔斯的功率。这种方法得到了米尔斯中常见的一些简单几何形状的剪切体积功率的计算的支持，并用于锥形盘磨机和CoBal磨机的剪切体积功率的计算。最后，通过引入破碎模型，给出了一个可用于搅拌米尔斯磨设计、操作和优化的方程。
A stirred milling model, based on the concept of shear–volume power, was developed and applied to geometries typically found in mineral processing systems. Generalising this model permits its use to model more complex mill geometries, such as those describing a tapered disk mill and the CoBal mill. Due to the additive property of the shear–volume power, the calculation of the power of complex mills is possible through geometric decomposition. This approach is supported by the calculation of the shear–volume power of a number of simple geometries commonly found in mills, and is used in the calculation of the shear–volume power of a tapered disk mill and the CoBal mill. Finally, by incorporating a breakage model, an equation that offers some usefulness in the design, operation and optimization of stirred mills is presented.
