Abstract The kinetics of slowing down of breakage rates for fine wet grinding of 20×30 mesh quartz fraction was investigated as a function of slurry concentration in a laboratory batch ball mill. It was discovered that the slowing-down effect occurred to all particle sizes in the charge and at any slurry concentrations even for very dilute conditions.

Rheology in mineral processing The majority of research on rheology in mineral processing has been focused on ore grinding. Shi and Napier-Munn (2002) have analysed the data of 45 surveys from full scale grinding mills, using regression analysis, and shown that slurry rheology affects industrial grinding.
In many mining operations, particularly northern open-pit mines, large seasonal variations in grinding slurry temperature can occur. It is shown in this paper that this temperature shift can cause a winter-time loss in autogenous grinding efficiency of as much as 20% if it is not controlled. Laboratory experimentation indicates that much of this effect is due to increases in …
Wet ultrafine grinding has been increasingly used for production of ultrafine powders in various industries. It has been known that slurry rheology significantly influences the grindability of industrial minerals in wet ultrafine grinding. This review represents some previous work with respect to slurry rheology in ultrafine grinding.

Abstract To determine the effect of slurry rheology on industrial grinding performance, 45 surveys were conducted on 16 full-scale grinding mills in five sites. Four operating variables—mill throughput, slurry density, slurry viscosity and feed fines content—were investigated.
In mineral flotation, rheological problems have limited the efficient upgrading of low-grade and complex ores. Since pulp and froth rheology are deemed to play different roles in influencing the separation performance, in this paper, a brief review on pulp and froth rheology in flotation is provided, with an objective of developing a basic understanding of rheology in flotation.
Rheometers Measuring the rheological properties of materials using a NETZSCH rheometer. A rheometer is a device used to measure the rheological properties of materials; rheology being defined as the study of the flow and deformation of matter, which describes the interrelation between force, deformation and time.

Food rheology is not equal to food texture but there is considerable overlap. The perception of the bolus of a chewed food in the mouth depends on the flow of the fluid and the disintegrated semi-solid food i.e. the rheology of the food. The perception also depends on the release or absorption of moisture and oil and grinding and fracture of

A simple criterion, the Grinding Index, was used to describe mill performance, defined as (1) Grinding Index = S D −S F 100−S F × where SD =percent passing a specified size (38 μm) in mill discharge, SF =percent passing a specified size (38 μm) in mill feed.
During paint manufacturing, the rheology of the mill base matters a lot to prevent loss of energy during the dispersing stage (also called grinding process). Rheology modifiers are added during the production process mostly before the dispersing stage - type and amount adjusted to the dispersing equipment - to obtain optimal flow behavior to ...
Abstract Suspensions of cellulose micro- and nanofibrils are widely used in coatings, fibre spinning, 3D and as rheology modifiers where they are frequently exposed to shear rates > 104 s−1, often within small confinements. High-shear rate rheological characterisation for these systems is therefore vital. Rheological data at high-shear rates are …
