Investigation on the influence of surface roughness on

2020-6-20 ensp 0183 ensp As presented in Table 1 there was a visual difference in the specific surface area between the two batches of magnetite particles 0 38 m 2 /g for the rod mill and 0 29 m 2 /g for the ball mill The calculated values of roughness parameters suggested that the magnetite particles milled by the rod mill were rougher than those milled by the ball...
