5. Pellets can be prepared by a special technique called Pelletization. This technique is referred to an agglomeration process that convert fine powder or granules of bulk drug or excipient in to small, free flowing, spherical or semi spherical pellets . This technique is needed to produce pellets of uniform size with high drug loading ...
Details
Iron ore concentrate pellets are traditionally hardened at high temperatures in horizontal grates and grate-kiln furnaces. However, heat induration requires tremendous quantities of energy to produce high-quality pellets, and is consequently expensive. Cold bonding is a low-temperature alternative to heat induration.

The document discusses sinter making technology used in iron ore mining. It describes how iron ore fines generated during mining cannot be directly charged in blast furnaces due to size restrictions. Sintering is used to agglomerate the fines into a porous mass that meets size requirements. The key steps in sinter making include: 1) raw ...
Details
The pelletization process is an established and economical route for enhanced utilization of the beneficiated micro-fines. The pellet feed is produced by mixing iron ore fines (-150 µm) with additives and a binder to meet the pellet quality requirements. The feed is then formed into spherical-shaped green pellets of 9–16 mm in diameter.

iron ore. His process involved grinding taconite to remove gangues and upgrading the iron ore (i.e., an ore beneficiation process). The resultant high-grade ore is in the form of fine particles, as small as 0.1mm or less, which are not suitable for sintering. This issue led to the use of pelletizing. Pelletizing plants are expected to play an

Pelletization of iron ore is seen as important for India's future as it allows for higher value exports and utilization of low-grade fines. However, many announced pellet plant expansion projects in India have been delayed due to issues around land, financing, iron ore availability and water. Solutions proposed include continued government ...

The present study evaluated the influence of these pellet fines on the sintering process. 5 experiments were conducted, by varying the pellet fines from 0 to 50% in the iron ore blend. It was found that the productivity decreased from 1.65 to 1.17 t/hr/m2 and sintering time increased from 27.5 to 34.5 min with increas-ing pellet fines.
