The milled powder of SPEX ball mill was 1000 times smaller in comparison with planetary for a ball milling period of 2 h. The size of the milled powder was <50 nm and 40 µm for SPEX and planetary ball mill, respectively. The average particle sizes are estimated around 25 nm and 15 µm for SPEX and planetary ball mill, respectively.

The grinding kinetics of three newly developed master alloys for steel powder metallurgy applications were investigated using a laboratory ball-mill. Non-first order grinding kinetic is observed for the three master alloys as the breakage rate increases with grinding time due to the work hardening of the ductile phase in the microstructure.
