installation for the production of a multicomponent binder sulfatique high-performance mechanical from gypsum and / or its derivatives, process for manufacture of such a binder and binder thus obtained

摘要

the invention is an installation for the production of a binder sulfatique from a powdery product. the installation comprises a dosing hopper (19), heating means (1) of the powder product, and cooling means (3) of the powdered material.the heating means (1) and (3) cooling associated with grinding means capable of obtaining a product in granular zone pulverulent to gypses, and means (2) for maintaining a saturated vapour pressure and a low du00e9terminees inside the heating means (1).the heating means (1) are composed of a variable speed pitch and furnace equipped with a burner block (8). the cooling means (3) are made of a special cooler designed to contain the maximum powder product, cooled, and are able to reduce the risk of hydration product is cooled by contact with the ambient air particulate.
