Vertical mixer

A vertical mixer is a type of process mixer in which the main axis of the mixing element is oriented vertically. The product is moved along this axis and repeatedly passes through different zones of the mixing chamber. This results in a spatial redistribution of the particles.

Vertical mixers often operate using a combined upward and downward movement of the material being mixed. The product is guided upwards along the wall of the vessel and then back downwards in the centre, or vice versa. This flow pattern promotes uniform mixing and reduces dead zones. Vertical mixers are used for dry bulk materials, powders and granulates. They are suitable for gentle mixing processes with low particle stress. Depending on the design, they can also be used for drying, tempering, reacting or impregnating.

Mixing quality depends on the geometry, speed, fill level and product properties. Vertical mixers are easily scalable and enable reproducible processes. They are used in the chemical, food, pharmaceutical, plastics and building materials industries.
