balling of iron ore balling formation

Balling drums liming

The balling area is where the powdered ore is mixed with water and rolled in rotating drums to create spherical balls. The green balls are spherical agglomerates nominally 12.5 mm in diameter, formed by rolling a moist mixture of finely ground iron ore concentrate, binder and sometimes a flux.

Water-bentonite interaction in balling of iron ores

Aug 01, 1973· Implications of these results in operation and control of industrial iron ore balling circuit are discussed. THE TONNAGE of iron ores agglomerated exceeded 100 million in year 1967 and is expected to touch 220 million mark by 1975 [1]. In most balling operations a small quantity, usually 5-15 lb/ton, of bentonite is added.
