The iron ore lumps were reduced to smaller sizes using sledge hammer. The iron ore was further crushed using jaw crusher and then pulverized using vibratory cup miller (Herzog model) in order to obtain fine particle sizes of about 100 mesh ( microns). The various equipment used for crushing and pulverization were set at 6 8 rpm.
