At the origin of the plaster, gypsum

The raw material is a mineral plaster rock called “gypsum”, which was formed in thick layers by evaporation of sea water there are 40 million years. These layers, separated by other rock masses are buried today.

Gypsum mining is carried out according to two principles:


The discovery of the plaster does not date from yesterday!
There are 40 million years, its raw material, mineral rock called “gypsum” has settled to form thick layers.
Today, gypsum is extracted from quarries in the open or underground galleries, then treated in plants located in their vicinity.
Is crushed it, it is cooked in low temperature ovens and is finely ground to obtain the powdered plaster.


Gypsum is an essential raw material for the development of all plaster based products. It is generally a matt white finely crystalline rock. Its purity and homogeneity play a vital role in the quality of plaster based products.


Stackers are directly connected to the belt conveyors ensuring the gypsum supply. The stackers can be mobile and installed on rails or wheels. They perform a precise storage enabling the homogenisation of gypsum. This equipment can adjust its height to reduce the risk of falling product.


Directly integrated to the structure of the storage warehouse, the tripper is mobile all along the building. The assembly is fixed to a conveyor belt which ensures the gypsum supply. The gypsum is then distributed on each side of the conveyor for storage. The movements of the tripper are automated and ensure a perfect homogenisation of the product.
