Rheological Effects in Grinding and Classification ...
Experimental work has been conducted on industrialscale 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.

Parameter effects on wet ultrafine grinding of limestone, Wet ultrafine grinding of a limestone powder ( 100 μm) has been investigated in a stirred media mill with respect to the effect of slurry rheologyThe grinding results obtained by various parameters (ie, molecular weight of a dispersant, solids concentration, additive dosage, addition ...
Slurry rheology of industrial minerals and its ... CORE
Wet ultrafine grinding of a limestone material (< 100 ¦Ìm) has been investigated in a stirred media mill with respect to the effect of slurry rheology. The results obtained by varying operation parameters (, molecular weight of a dispersant, solid concentration, addition dosage, addition method and bead load) are evaluated in terms of energy efficiency and the fineness.

Abstract. In Northern Brazil, bauxite pulp is transported through pipelines to the plant where alumina is produced. In slurry transportation through pipelines, knowing the yield stress value is essential for the pumps and pipeline design. Yield stress is the minimum shear stress and corresponds to the first evidence of flow.
Rheological Effects On Ultra Fine Grinding In
Ball Mill. Ball mill is the key equipment for grinding after the crushing process, which is widely used in the manufacture industries, such as cement, silicate, new building material, refractory material, fertilizer, ferrous metal, nonferrous metal and glass ceramics and can be used for the dry and wet grinding for all kinds of ores and other grindable materials.

Predicting Viscosity of Limestone–Water Slurry
The rheology behavior of the slurry is essentially to be controlled in many industrial processes such as transportation of slurries, dewatering and wet grinding [2]. A number of theoretical and
DEVELOPMENTS IN FINE AND ULTRAFINE GRINDING ...
The major challenge in fine and ultrafine grinding of minerals is to achieve the required product size at an affordable energy cost and high mill throughput. Fine and ultrafine grinding processes are defined in this paper as those producing milled products at 80% passing 20 microns and 7 microns, respectively.
Predicting Viscosity of Limestone–Water Slurry
The rheological behavior of limestone–water slurry samples was investigated for different volume concentrations, particle size distribution and slurry temperature. Experiments were conducted over a range of volumetric solids concentration (Q= ) in shear rate range of 1300 s 1 . The slurry showed Newtonian behavior up to a volumetric solids concentration of vol. %, beyond ...
