the effect of slurry rheology on fine grinding in a

slurry rheology for wet grinding applications is given in He et al. (2004). They suggest that optimization of slurry rheology for a mill may provide increased throughput, energy efficiency, and fineness of product. Tower mills consist of a stationary, cylindrical grinding chamber filled with grinding media (such as steel or ceramic balls).

Abstract Experimental work has been conducted on industrial-scale wet comminution devices and hydrocyclone classifiers to investigate the effects of slurry rheology on their performance. Grinding performance is shown to be influenced not only by the absolute value of apparent viscosity and an inferred yield stress, but also by the rheological type of the discharge slurry.
