effect of ball milling on particle size hindi

Specific surface area (SSA) and particle size (PS) measurements exposed the effect of ball milling on the CaP compounds and CPC powders. X-ray diffraction revealed no effect of ball milling pathways or milling time on the composition of CPCs or the starting materials, but affected their crystallographic properties

    A model describing the mechanical comminution (ball milling) of crystals to nanocrystalline powders is proposed. It is shown that a fraction of the energy deposited in the processed material is spent for the creation of microstresses ɛ, which slows down the comminution process.
