Iron Ore Pellets Iron Ore

Iron ore pellets can be made by two different processes, the Straight Grate process and the Grate Kiln process. The Grate kiln system consists of three machines; a traveling grate, a rotary kiln and an annular cooler which heats, hardens and cools the ore respectively.

Effect of adding limestone on the metallurgical properties

10/08/2015· The most common fluxing materials for iron ore pellet production are limestone (CaCO 3), dolomite (Ca,Mg(CO 3) 2) and olivine (Mg 2 SiO 4), but sometimes magnesite (MgCO 3) is also used. Fluxing agents are used not only to enhance slag formation, but also to improve softening and melting properties and to increase the reducibility of the burden materials before softening (Dwarapudi et al

Use of Iron Ore Pellets in Blast Furnace Burden – Pellets constitute about 70 % of the blast furnace burden. Initially acid pellets (DRI grades) were produced and used in blast furnaces. In the mid 1980s, a number of pelletizing and blast furnace trials were conducted to evaluate the benefits of limestone dolomite fluxed pellets. Influence of flux additives on iron ore oxidized pellets. 2010

Development on Iron Ore Pelletization Using Calcined Lime

This study is concentrated on optimization of MgO (olivine) flux addition and basicity and finally used calcined lime in place of limestone in developing good quality iron ore pellets with combined flux. It is found that calcined lime fluxed pellet without bentonite and limestone shows very good dry compressive strength (3.5 kg/pellet) and improved green compressive strength (1.5 kg/pellet

Iron ore pelletizing systems minevik

Iron Ore Pellets are formed from beneficiated or run of mine iron fines. The iron is usually ground to a very fine level and mixed with limestone or dolomite as a fluxing agent and bentonite or organic binders as a binding agent. If the ore is a Hematite ore, coke or anthracite coal can be added to the mix to work as an internal fuel to help fire the pellets. This mixture is blended together

The pellets were produced using a tire pelletizer with a three-phase 05 cv (0493 hp) motor Three types of pellets were produced, as described below in Table 1 To perform the tests 200 kg (442 lb) of iron ore were used The binder was used at ratios of 6kg metric ton of ore, 54 kg metric ton of limestone and 135 kg metric ton of coal

Effect of adding limestone on the metallurgical properties

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

CHEMICAL GRADE LIMESTONE | Iron & Steel | Carmeuse

Our chemical grade limestone is used in the ironmaking process to produce the slag, which removes impurities from the iron ore while making liquid pig iron. Our limestone is added to iron sinter and pellets to add flux and promote agglomeration in your products. Blast furnaces can add limestone directly to the burden to promote slag formation and protect the refractory.
