Beads from 1.5-2.3 mm can be manufactured but not all will be spherical. They are more expensive due to small yields for this size range.


This dust free bead is intended to be used as a grinding media in most milling applications that require very low contamination levels from wear. Choose from several grades of spherical grinding media beads from Norstone. Products that benefit from this type of media are generally low viscosity and shear sensitive. Norstone makes no warranty regarding the specific use of this bead or intended end use for the products made with this bead


SSDP is available from 1 kg up to 20 kg packaging in 1 kg increments. All packaging is in FDA approved foil pouches which are shipped in an anti-static plastic bag.
