Hosokawa Micron provides excellent mixing and drying solutions for gypsum powder, for example in the production of fertilisers or construction materials such as plaster (plasterboard) or as a concrete additive.

Gypsum drying

In most cases, the dry gypsum needs processing. Sometimes the water hydrate needs to be removed, resulting in a hemi-hydrate or anhydrite form. Whatever form is required (di-hydrate, hemi-hydrate or anhydrite), it’s always very important to control the hydration state. The dryer you select should be able to control this state closely. One excellent choice would be the Micron Dryer, which is capable of producing hemi-hydrates.

Gypsum mixing

When producing construction materials, water is mixed to the hemi-hydrate to form a di-hydrate. This reaction can be accelerated by adding a small amount of water to the powder before adding the full complement of water. The Schugi® Flexomix is perfect for this kind of wetting or moisturising. By bringing each particle into contact with a small amount of water, the particles become more receptive to the rest of the water that is required.
