Re: Will prior densification of components affect the homogeneity of mixing?3 April 2013 at 10:57am Last edited: 23 April 2013 at 2:16pm
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.
The answers by this expert are based on the best available interpretation of the information provided. The consequences of the application of this information are the responsibility of the user. If clarification is needed, please submit a further question.
Currently in our process we do wet mixing of two raw materials. Particle size of the components are in the range 0.8 to 1 micron. Bulk density of components are in the same range. Do you think prior densification of any component will have effect on the homogeneity of mixing?
Have an insight or suggestion?
