The wear-resistant products in the most demand are grinding balls, mill linings, industrial pump parts, and bucket teeth. Grinding balls for breaking up bulk and friable materials are widely used at enterprises in the mining and processing industry, in the ore mining and smelting industry, and in the energy and cement industries.
NLMK began implementing HPGR technology in each of the plant's four process lines in 2016. The first four grinding rolls supplemented traditional cone crushers and ball mills, and enabled the plant to boost the productivity of the sections by 12.5% and to grow iron ore concentrate output by 1 million mt to 16.6 million mt/y.
Likewise, Hebbar (2011) has studied the grinding wear behaviour of austempered ductile iron as media material in the comminution of Kudremukh haematite iron ore in a ball mill. The grinding experiments were conducted under different pH conditions, i.e. pH = 7.0 and pH = 8.5, while keeping other parameters fixed, at a mill speed of 74 rpm for 1 hr.
