Two large volume agate mills (reserved for ultramafic rocks), one small agate ball mill, and one ceramic shatterbox/agate ball mill. There is also a range of verysmallvolume ball mills (steel and agate) available for radiogenic isotope preparations (not shown). These mills are used for trace and ultratrace analytical preparations.

Short multiwall carbon nanotubes can be obtained by ball milling. The average length of the ball milled carbon nanotubes, synthesised by decomposition of acetylene on different types of supported metal catalysts, is ca. μm. The cleavage was caused by the collision between one agate ball and the nanotube powder contained in an agate mortar.

In order to prevent excessive abrasion, the hardness of the grinding jars used and of the grinding balls must be higher than that of the material used. Normally, grinding jars and grinding balls of the same material should be chosen. For example, 250ml agate ball mill jar, normally is matched with 250g mixed agate grinding balls.
