The answer to this question probably has multiple answers depending on related factors. However, the simple answer is that if "wet mixing" means forming a liquid suspension of small, slowly settling particles, densification should not make a significant change in the homogeneity of the mixture.

However, if the solids concentration is 20% or greater, interaction between particles could be significant enough to cause changes in the "fluid" behavior of the suspension. Densification usually means that the current particles 0.8 to 1 microns will be compacted together forming larger particles. Larger particles in a slurry may move more easily than fine particles, but they will settle faster.

The real answer to this question may be in a range where testing is necessary to decide how interacting properties affect the behavior of the mixture. Testing might be done on a smaller than production scale to avoid unwanted waste or expense.
