1973-8-1  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.

1976-9-1  The balling drum circuit as conventionally used in iron ore pelletizing plants is analyzed from a control engineering viewpoint and a simple model presented. An analysis of the model indicates that the “surging” phenomenon generally encountered in these circuits is actually a limit cycle oscillation. With this knowledge, and using classical ...

Preparation of Iron Ore Micro-pellets and Their Effect on ...

2018-6-13  At present around 6–7% of iron ore slimes, out of total production, are being generated and accumulated at iron ore mine sites of National Mineral Development Corporation Limited, India. The accumulated slimes of finer size and relatively inferior grade should be utilized in an economical way for sustainable mining. These slimes can be agglomerated into micro-pellets for subsequent use in ...
