The inplace roll grinder can achieve tolerances to 0.0005" on diameter, concentricity, and straightness, with finishes as fine as 12rms, depending on the grit of the grinding medium. Crowning attachments are optional, and the roll grinder can be fitted for steel, cast iron, rubber, felt, husk, wool, or cotton filled rolls.

In the present study, the effect of grinding media shape on breakage parameters was investigated. Balls and cylpebs were used as the grinding media. It was observed that the grinding of quartz obeyed first‐order breakage kinetics in the case of balls and cylpebs. Higher breakage rates were noted with cylpebs than with balls. Furthermore, it was found that the primary …

media density is beneficial to obtain finer products. Thus, zirconia balls (Ø=3 mm, Ø=5 mm and a mixture with half of each) and cylinders (Ø=5 mm x 5 mm) were used as grinding media. Grinding in a planetary mill is a high-energy process that occurs in jars, which have a high thermal barrier (due to their ceramic coating).

Why grinding? To manufacture precise products with corresponding shape or po-sitional tolerances or after heat treating a material, it is essential to fi ne grind a workpiece in or-der to obtain the required surface fi nish quality while stay ing within the correspondingly low shape, positional, and dimensional toler-ances.
