The coagulation process in the kaolin slurry gives rise to voluminous aggregates of kaolin particles, where a great deal of water is fixed.  A modification of the physico-chemical environment of the slurry by addition of a peptising agent produces repulsive forces between particles. It results in destruction of the aggregates and water originally fixed in aggregates is liberated, the viscous friction can play a larger role in the slurry, which is liquefied. To prove this process kaolin slurry with and without the peptising agent was measured on experimental pipeline loop. It was demonstrated that even very low concentration of peptising agent results in a significant reduction of the apparent viscosity and of the yield stress.
