Agglomeration of Particles

Agglomeration is the formation of aggregate by the sticking together of feed and/or recycle materials, and it includes the formation of agglomerate nuclei. The main objective in agglomerating fines being the conversion of ores, minerals and chemicals of undesirable fineness into agglomerates characterised by a size consistency desirable for subsequent use or processing. In metallurgical ...

Pelletization - an overview | ScienceDirect Topics

The ore is crushed, ground, and concentrated in several steps to very small grain size—e.g., over 75% less than 45 μm. Binder (bentonite or organic) and possible additives are fed in the slurry and mixed before filtering. The filter cake is transported to large balling drums or balling discs to be rolled to green pellets.
