This is because alumina balls have larger surface roughness than steel balls. Hence, the specific surface areas of the corn stover after milling for 60 min were 395 and 896 m 2 /kg for steel and alumina balls, respectively. Nevertheless, steel balls showed the highest size reduction effect in short milling time due to their higher specific ...
