Then the iron ore pellets will sent through metallic conveyor into the furnace to undergo heating process at 1200 degrees. After the heating process, the heated base mix will converted into a semi liquid cake. Using a sinter breaker machine the cake is break into small pellets. Finally these iron ore pellets under goes cooling in the cooling Indian iron ores are suffering from high amounts of alumina and loss on ignition (LOI), which are deleterious constituents in both the pelletizing as well as iron making processes. Iron ore fines utilized in pellet making consist of alumina in the range of 3.20–3.35% and LOI in the range of 3.50–3.70%.

Deposit formation in the coal-fired rotary kiln is frequently found in the production of fluxed iron ore pellets by the grate-kiln process and affects normal production. In this paper, the effects of pellet basicity (CaO/SiO2 mass ratio) on the simulated deposit formation were investigated. The results show that the porosity of deposits samples increases from 30.8 The three common processes used in iron ore pellet production are the shaft furnace process, the straight grate process, and the grate-kiln process. 8 As the dominant process for iron ore pellet production in China, the proportion of iron ore pellets produced by the grate-kiln process has exceeded 70%. 9 Deposit formation in a rotary Effects of Pellet Basicity on the Simulated Deposit Formation

Iron ore pellets and Pelletizing processes. Pelletizing is a process that involves mixing very finely ground particles of iron ore fines of size less than 200 mesh with additives like bentonite and then shaping them into oval/spherical lumps of 8-16 mm in diameter by a pelletizer and hardening the balls by firing with a fuel. It is the process of Iron ore pellet reduction experiments were performed with pure hydrogen (H2) and mixtures with carbon monoxide (CO) at different ratios.
