Drying Of Gypsum Building Materials
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 rotary dryer, which is
capable of producing hemi-hydrates.
Gypsum mixing
For the production of 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 Hengyang continuous mixer is perfect
for this kind of wetting or moisturizing. 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.
