On fragmentation and agglomeration phenomena in an ultrafine wet
This study deals with ultrafine wet grinding of calcite particles in a stirred bead mill. As the size decreases during the process, the particles are strongly subjected to attractive interparticle forces leading to an aggregation phenomenon that generates an increase of the suspension viscosity.

Mechanical activation of steel slag to prepare supplementary
The results demonstrate that the grinding process mostly affects the PSD and morphology of steel slag, but has minor effects on the mineral composition and crystallinity. The PSD of steel slag after wet-grinding is always narrower and more uniform than that of steel slag after dry-grinding under identical grinding times. The PSD alone. …

What is Grinding?
Grinding is an abrasive machining process that uses a grinding wheel or abrasive belt as the cutting tool. It is commonly used to remove material from a workpiece, to produce a smooth finish on the surface of the workpiece, or to remove burrs from the surface. Grinding can be performed wet or dry, and can be performed on a variety of …
