Such ranges tend to afford an optimal balance betweenefficient particle size reduction and media erosion but are in no waylimiting Theattrition time can vary widely and depends primarily upon the particular mechanical means and processing conditions selected.
In general, suitable polymeric resins are chemically and physically inert, substantially free of metals, solvent, and monomers, and of sufficient hardness and friability to enable them to avoid being chipped or crushed during grinding.
