Rheological behaviour and microstructural properties of dark …
According to Servais, Jones, and Roberts (2002), surface roughness influences the rheology of suspension. In a ball mill, particles were ground through short contact between sugar/cocoa particles and metal balls and/or wall of the tank, while in a roll refiner particles were refined through a relatively longer contact between solid particles ...

Most of the mills used in ultrafine grinding are stirred media mills, rather than conventional tumbling ball mills [3]. ... However, the mechanisms of action of the dispersants with various molecular weights on the slurry rheology in a stirred media mill are sufficiently unclear. Therefore, further studies on this aspect should be carried out.

Effects of slurry rheology on industrial grinding performance
Apparent viscosity was characterised at a shear rate of 200 s −1 to represent the viscosity of each discharge slurry. The selection of 200 s −1 was based on an estimation of the shear rate range inside a typical ball mill, derived from two types of ball motion, cascading and cataracting (Shi and Napier-Munn, 1999).. A simple criterion, the …
