Iron ore fluxed pellets and their physical .

01.06.1985 · As limestone particles and pellets are weaker than those of iron ore, increasing the amount of limestone in the pellets from 10 to 20% led to a slight decrease in the crushing strength of fluxed pelletsFigure 7 shows this trend more clearly when the material was pelletized without any binder.

Fluxed Pellets Production

Pellet production was found to increase in proportion to the amount of mill scale added. With no mill scale, daily fluxed pellet production was about 5100 tons, with 15 per cent mill scale addition, an average production rate of 6800 tons per day was achieved while the record daily tonnage of fluxed pellets was 7118 tons.

BEHAVIOUR OF COATINGS ON OLIVINE FLUXED PELLETS IN .

Different coatings on olivine fluxed blast furnace pellets were examined in LKAB's experimental blast furnace, Luleå. The aim of coating is to decrease dust generation, prevent sticking and to bind alkali for smoother operation. The coating materials were kaolinite, bauxite, olivine and limestone. Uncoated pellets were studied for reference.
