High chrome grinding Cylpebs is a casting alloy grinding media contain 10-28% chrome. this grinding media used in Ball mill / SAG mill for Mining / Cement and other industry, to mill & crush ore/ coal / sand / cement and other material.
Its have good micro structure by Alloy casting, and have good hardness and broken rate through heat treatment. So used this 10-28% Cr grinding Cylpebs will get lower wear rate and reduce the ball mill downtime.
