Wet ultrafine grinding of a limestone powder (lt; 100 m) has been investigated in a stirred media mill with respect to the effect of slurry rheology. The grinding results obtained by various
Summary: An investigation was made of the effect of slurry consistency on the behavior of wet grinding in a batch laboratory ball mill. Using the wellknown batch grinding kinetics model in analyzing the test data, it was found that wet grinding of quartz and copper ore gave nonfirstorder acceleration of breakage rates at low slurry densities (geq60 volume % solids).
The kinetics of slowing down of breakage rates for fine wet grinding of 20#215;30 mesh quartz fraction was investigated as a function of slurry concentration in a laboratory batch ball mill. It was discovered that the slowingdown effect occurred to all particle sizes in the charge and at any slurry concentrations even for very dilute conditions.
The effect of slurry rheology and ball coating characteristics on the abrasive wear of grinding media and the rate of grinding were studied using 10 mesh quartzite in laboratory marked ball wear tests. Pulp viscosity was found to be closely related with both the thickness and physical characteristics of the coating affecting abrasive wear.

#0183;#32;Abstract To determine the effect of slurry rheology on industrial grinding performance, 45 surveys were conducted on 16 fullscale grinding mills in five sites. Four operating variablesmill throughput, slurry density, slurry viscosity and feed fines contentwere investigated. The rheology of the mill discharge slurries was measured either online or offline, and the data were processed

#0183;#32;Mechanisms of slowingdown effect in fine wet grinding were hypothesized to involve the different roles of slurry rheology in different grinding regimes. They are reduction of particle capture efficiency due to fluid drag for Regime I, reduced efficiency of stress transmission due to ball coating by particle layer for Regime II and reduction of ball collision frequency due to ball adherence
To determine the effect of slurry rheology on industrial grinding performance, 45 surveys were conducted on 16 fullscale grinding mills in five sites. Four operating variablesmill throughput, slurry density, slurry viscosity and feed fines contentwere investigated.
The significance of fine wet grinding in many industrial applications is obvious, but available data in this area are quite limited. This paper reports further results on the kinetic analysis and mechanisms underlying the slowing down of breakage rates in fine wet grinding, with emphasis on the effect of slurry rheology in a batch laboratory
