In agglomeration using heat (sintering), atoms and molecules begin to migrate across the interface where particles touch each other. This happens at a certain elevated temperature, which is different for various materials. While still in solid state, diffused matter forms bridge-like structures between the surfaces, which solidify upon cooling.
These topics are dealt with in the chapter. Technologies, such as the hybrid pelletized sinter process (HPS) and composite agglomeration process (CAP), have been developed to utilize finer-sized ore through sintering and have gained considerable attention in recent years as these avoid conventional pelletization; these are also described.
Agglomerators. FEECO has been building agglomerators since 1951. We design our drums according to the needs of your unique process and material. agglomerators are an ideal solution for high capacity agglomeration operations, or when agglomeration needs to be combined with a chemical reaction, such as in the production of granular fertilizers.
Sintering 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.
