Speed Grinding Reduced

Literature indicated that at high grinding speed (160 m/s), brittle to ductile transition takes place for alumina; and alumina can be ground effectively with reduced amount of brittle fracture at high grinding speed , ,.However, at moderately high grinding speed of 80 m/s, the brittle fracture has been widely observed and reported.
