Calcining processes for natural and synthetic gypsum
The resulting stucco is suitable for the production of plasterboard, gypsum fiberboard and gypsum wall blocks. A hammer mill can process moist FGD gypsum, pre-crushed natural gypsum, or a mixture of both. Recycled gypsum plasterboard that has been crushed and stripped of paper can also be fed into the process.
Recycling of plaster of Paris
Preparation of plaster of Paris to recycle the powder . The same process was used in mixing the recycled powder with water to produce positive model casts for the second, third, fourth and fifth recycling rounds respectively. The casts were broken manually and later pressed through the hardened steel plates of a pressing machine.
Circularity – Eurogypsum
Gypsum being an eternally recyclable mineral, the European gypsum industry is committed to a circular economy. To use mineral resources in the most effective and responsible way, especially with an anticipated decline in the availability of synthetic gypsum from coal power plant desulphurisation in the coming decades, our industry has made considerable efforts …
