MSE Supplies offers Cylindrical 92% Alumina Grinding Media, which is very reliable in the case of high temperature corrosion. It is widely used in different types of ceramics, porcelain glaze, glass, chemical and other applications of thick and hard material finishing and processing. Its crushing/grinding efficiency and wear resistance are much better than ordinary pebbles or natural pebbles.

You may see some black spots on the alumina ball which is due to the contact of SiC frame during manufacturing. It will not affect the milling performance.
