Grinding Media

_D705408Ceresist stocks and distributes spherical and cylindrical high-purity alumina grinding media for wet or dry milling.  The hard, imperveous, wear-resistant alumina ceramic is mills faster with negligible contamination. It’s not affected by most chemicals, is non-conductive, non-magnetic, and chip-resistant.
