Influence of velocity gradient on optimisation of the aggregation process and properties of formed aggregates. Part 2. Quantification of the influence of agitation intensity and time on the properties of formed aggregates
Original language description
The follow up research into the IHDS process was carried out with a Couette device. The effects of the agitation intensity (G) and the agitation time on the kinetics and the mechanism of the aggregation process were studied. The very favourable influenceof high agitation intensity for the formation of more compact and dense aggregates was confirmed. It was also proved that the agitation intensity and time are the inherent means influencing the properties of the resultant aggregates such as their size,shape, density and homogeneity. It was confirmed that the aggregation process passes through a minimum. Furthermore, it was verified that the aggregation process takes place in four consecutive phases, namely the phase of a) formation, b) compaction, c)steady (equilibrium) state and d) inner restructuring. The pattern of the aggregates development in these phases remains the same irrespective of the magnitude of G applied but the time at which these phases are completed is G dependent.
