Limestone Addition In Iron Ore Pelletizing

Effect Of Limestone Addition On The

Limestone addition increased the reducibility of the pellets. Swelling and cracking of the pellets during dynamic reduction was slightly increased with limestone addition. The final reduction degree was higher in the reduction-softening test named ARUL with the fluxed pellets compared to the non-fluxed ones,

Iron Ore Fluxed Pellets And Their Physical Properties

Jun 01, 1985 Jun 01, 1985 This is because, as stated before, the cementing action of bentonite improved the resistance of pellets to breakage- This is particularly noticeable in the case of limestone pellets as well as fluxed iron ore pellets. 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

Effect Of Adding Limestone On The Metallurgical Properties

Aug 10, 2015 One of the most common fluxing materials for iron ore pellet production is limestone, which is mainly calcium oxide (CaO). In this study, the effect of adding limestone on the metallurgical properties (reducibility, swelling, cracking, softening temperature, Low-Temperature Disintegration, Cold Crushing Strength) of acid iron ore pellets was investigated using a comprehensive set of metallurgical laboratory tests.
