Self-agglomeration mechanism of iron nanoparticles in a …
Aided by self-agglomeration, a two-stage reduction process conducted at a higher temperature (600 °C) than the single-stage process resulted in an enhancement of the k constant to more than twice that of the single-stage process. A force balance model coupled with the reduction kinetics of Fe 2 O 3 is first proposed to explain the self-agglomeration …

Agglomeration - an overview | ScienceDirect Topics
The agglomeration process consists of the transportation and collision of particles, and the attachment of the particles, followed by either disruption or cementation of the attached particles. The cemented particles are agglomerates. If the supersaturation is zero, no cementation occurs and all loosely agglomerated particles fall apart again.

ABSTRACT In steel industry and in mines, a significant amount of ultra-fines waste iron oxides and iron ore fines is generated. Utilizations of these fines are required to reduce the environmental hazards and conserve the natural resources. Some of these fines are normally used in sintering practice. However, sintering has a limitation of accepting ultra-fines materials.

The most common agglomeration process is the sintering of fine ore. As a rule, larger amounts of circulation material are used in the sintering plant. This often leads to increased emissions. A good solution here is a cloth filter system with a semi-dry sorption process. Küttner works here with Lühr in a very close cooperation.
