    Investigation on the particle size and shape of iron ore

    High pressure grinding roll (HPGR) and ball mill are the most widely used machinery to increase Blaine specific surface areas of pellet feeds. Some pelletizing plants which use HPGR for regrinding are CVRD/Brazil, WISCO mineral/China, and Ardakan/Iran. In ball milling, particle size reduction occurs by impact and attrition breakage.Crushing devices hold feed material between two solid surfaces and apply sufficient force to fracture or deform that material. Primary crushing operations takes boulder size feeds (20 to 100 inches) and reduces the material to secondary crusher feed size (1 to 20 inches) or mill feed size (0.5 to 3 inches).
