The FEECO Agglomeration Handbook

Key techniques in non-pressure agglomeration include: Pelletizing: A process whereby material fines are rolled into uniform pellets with the help of a binding agent. Micro Pelletizing: A process in which material fines are mixed with a binder to form small agglomerates, or create "seed pellets" to prepare the material for pelletizing.

Recent Advances in Pelletization Techniques

The binder may be added as molten liquid or as dry powder or flakes and the binder may be heated by means of hot air or by heating jacket above its melting point. As the molten binder solidifies by cooling, dry agglomerates are formed. Melting points of the binders used in melt agglomeration ranges from 50oC to 80oC.
