Kinetics of ballmill grinding of powders produced
2011923 · Mathematical one and twoparameter models used to describe the grinding of structural materials and ores are analyzed with the purpose of their potential application to describe the grinding of metal powders. Experimental verification is carried out on PZhR3 iron powders (as per GOST 9849–88) and ShKh15 steel powders resulting from the disposal of bearingproduction waste.
Ballmill grinding kinetics of master alloys for steel
2011710 · The grinding kinetics of three newly developed master alloys for steel powder metallurgy applications were investigated using a laboratory ballmill. Nonfirst 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.
