What s the Difference Between Ball Mills and Rod Mills

Nov 19 2019 · The rod mill adopts overflow type and open type discharge does not use grate type discharge. The diameter of the rod mill discharge end is larger than that of the same size ball mill. When the rod mill speed is lower than the working speed of the same size ball mill the medium in the rod mill Herein a versatile approach is demonstrated to skilfully synthesize Co 2 P nanoparticles encapsulated in nitrogen doped hollow carbon rods (Co 2 P/N-HCRs) by ball-milling following simple heat treatment. In particular the Co/C content has an extremely important influence on the formation of Co 2 P/N-HCRs with tubular structures.
