Effect of fluid–particle-interactions on dispersing nano ...

2010-4-1  The stress intensity in a stirred media mill is proportional to the kinetic energy of the grinding media and inversely proportional to the stressed particle mass . Consequently, i in case of stressing single particles at constant operating parameters of the mill the stress intensity is inversely proportional to the third power of the particle size.

Stirred Milling Technology – A New Concept in Fine

2019-5-8  STIRRED MILLING TECHNOLOGY Mill structure The vertical stirred media grinding mill uses a grinding chamber filled with small beads whereby comminution takes place by attrition between the beads. The stirring effect is caused by rotating discs mounted on a shaft. There are also stationary discs on the mill body positioned in between each

Nano-milling of pigment agglomerates using a wet stirred ...

The present study concerns the production of pigment nanoparticles in a wet-batch stirred media mill with polymeric media. The breakage kinetics and mechanisms were investigated using size-discrete population balance models (PBMs). The temporal variation of the particle size distribution was measured via dynamic light scattering.
