Agglomeration of particulate materials. |
摘要 |
<p>Particulate material such as iron ore is agglomerated into pellets or other agglomerates by being homogeneously mixed in the presence of moisture with a binder followed by agglomeration of the moist mixture, and the binder comprises a water soluble anionic polymer having intrinsic viscosity of from about 2 to about 7 dl/g and containing 5 to about 20% by weight carboxylic monomer groups (measured as sodium salt). The preferred polymer of is the copolymer of acrylamide and 5 to 20%, preferably 5 to 15%, sodium acrylate. The binder may also comprise bentonite.</p> |
