CONSIDERATIONS ON AGGLOMERATE GROWTH PROCESSES: STUDIES ON AGGLOMERATION IN WATER (2ND REPORT).

Agglomeration experiments were carried out using BaSO//4 as model particles, sodium oleate (NaOl) as the surface active reagent and kerosene as the bridging liquid agglomerate growth processes are classified into three patterns. The pattern 1) agglomerates were formed immediately after the experiment started and they gradually grew to certain sizes after which agglomerate growth slowed down. In pattern 2) micro-agglomerates were formed and after a certain aging time they grew to large agglomerates with intermediate size agglomerates also present. In pattern 3) micro-agglomerates were formed and after a certain aging time they grew to large agglomerates with almost no intermediate size agglomerates. Simulations of these patterns were conducted using population balance equations.
