Industry/University Cooperative Research Activity: The Roleof Slurry Rheology in Size Reduction and Material Transport in Tumbling Ball Mills

在连续磨中，浆料流变学对固体的输送和粒度的减小都起着重要的作用。然而，尽管它们很重要，但令人惊讶的是，缺乏这些流变效应精确性质的定量信息。本项目的目的是对浆料流变对翻滚球磨机中物料输送和粒度减小的影响进行系统调查。拟议的研究包括浆料流变学行为的基础研究，浆料流变学对磨机中颗粒破碎的影响的定量评估，以及连续磨机中物料输送的流变学方面的研究。该项目的最终目标是开发一种改进的连续磨机尺寸减小过程的物理/数学处理方法。

Slurry rheology plays a significant role in both the transport of solids and the size reduction process in continuous grinding mills. Despite their importance, however, there is a surprising lack of quantitative information of the precise nature of these rheological effects. The objective of this project is to carry out a systematic investigation of the effects of slurry rheology on material transport and size reduction in tumbling ball mills. The proposed research includes fundamental studies of the rheological behavior of slurries, quantitative evaluation of the effects of slurry rheology on particle breakage in mills, and investigation of the rheological aspects of material transport in continuous mills. The ultimate goal of the project is to develop an improved physical/mathematical treatment of the process of size reduction in continuous grinding mills.
