2. Technological aspects of mixing divided solids

2.1 Technical feasibility of a blend

Mixing divided solids with different physical and physico-chemical properties is, above all, a technological problem that cannot be summed up simply by bringing the "phases" into contact and agitating the whole. The complexity of this operation is undoubtedly due to the extreme diversity of granular and powdered media, and more specifically to the difficulties encountered in characterizing their suitability for mixing.

Given a system of products to be mixed, the "engineer's art" will lie in choosing the technology best suited to the problem. To do this, it will be necessary to consider both the mixing mechanisms induced by the different mixing technologies, and those favored by the very nature of the products. Neglecting...
