3. Conclusion

As we have seen in this article, industrial polymer blending tools are extremely varied. The modeling of these tools has hardly ever preceded their design and construction, but today it sheds light on their operation, enabling us to better understand them, choose the most suitable tools and, if necessary, optimize them.

Controlling mixing operations still poses a number of problems, for example when the filler ratio is increased, when the number of ingredients is multiplied (several polymers and/or several fillers of different kinds) or when low-viscosity liquid reagents are introduced...

In particular, the recycling of shredded scrap from the manufacture of multilayer products poses the problem of mixing fillers B of a particular nature with a polymer A. These fillers, which are made up of heterogeneous micro-agglomerates (e.g. a mixture...
