how to select grinding media. Three real factors controlling the choice of grinding media: How big it is, (diameter, usually expressed in millimeters or mesh size) How heavy it is, (specific gravity, typically in g/cm3) What it is made of (strength, wear life, abrasiveness, inertness, cost) Of these, only size and density control its ability to ...

Grinding media density. The range of specific gravity for commercially available grinding media runs from sp.gr. 1.0 for plastics to sp.gr. 15 for tungsten carbide. It makes sense that you wouldn't select a very light grinding bead for a highly viscous system or a very dense grinding bead for a low-solids aqueous suspension.

MEDIA SELECTION Choice of grinding media depends upon several factors, some of which are interrelated. • Specific gravity. In general high-density media give better results. The media should be denser than the material to be ground. When grinding some slurries, media with higher density may be required to prevent floating. • Initial feed size.
