Silicon Nitride Grinding Media Balls

Silicon nitride grinding media ball has unique features such as high strength, good wear/corrosion resistance, high temperature resistance, electrical insulation and non-magnetic. Compared with other grinding media, it has lighter weight (60% less than steel), lower thermal expansion and total operation cost. Its high hardness can meet the vast majority of metal powder crushing and refining. It is a ideal grinding media when high hardness, less contamination and less abrasion is required. Choose between 3 mm - 25 mm in size for the silicon nitride media.
