Iron ore pellets are marble-sized balls of iron ore that are fused with clay for transportation and used in steel manufacture. The process of making pellets from iron ore is called pelletizing. The manufacture of steel from low-grade iron ore involves processes like mining, crushing, separating, concentrating, mixing, pelletizing, and shipping.

When leaving the drum, the pellets are screened, and all pellets with too small a diameter are fed back to go through the drum once more. Oversized pellets are crushed and recycled. ... Therefore, the iron ore pelletizing process may be described as a chain of several sub-processes which may depend highly upon each other's performance.
Iron ore pelletizing is an essential industrial process that transforms powdery iron ore into uniform, robust pellets, serving as a premium feedstock for blast furnaces and direct reduction reactors. This process has witnessed significant advancements since its inception, primarily driven by the escalating requirements of the steel industry, which demands higher quality and more ...
2. Introduction To Pelletisation Process Pellets are spherical balls formed by the agglomeration of natural or ground iron ore fines in the presence of moisture and binder These green balls of 5 – 20mm size are then dried, preheated and fired at 1250 – 13500 C Bonding is developed between the fine ore particles at such high temperatures Additives like Bentonite, …
Our iron ore pelletizing systems combine the best features of both technologies to provide the most modern plant and to produce pellets at the lowest cost and highest quality. Pellet plants sized from 1.2MTPA to 9MTPA; Engineering and …
Once the blending is complete, the resulting filter cake progresses to the balling area. In this phase, the ore is agglomerated on pelletizing discs (also known as balling discs) or balling drums, producing green or unfired pellets. The primary objective is to shape the ore into a consistent size, ideally ranging between 9-16mm.
The iron ore pelletizing process consists of three main steps: Pelletizing feed preparation and mixing: the raw material (iron ore concentrate, additives —anthracite, dolomite—and … Pelletising – Hub of pelletizing industry's people
Five iron ore agglomeration technologies can be defined: briquetting, nodulization, extrusion, pelletization and sintering. Sintering and pelletization are the most important agglomeration technologies, in this way, in the EU-27, 14 countries operate 34 iron ore sinter plants with 63 iron ore sinter strands, producing in the first decade of the ...

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.
