Les diatom\u00e9es proviennent de roches s\u00e9dimentaires tr\u00e8s poreuses, constitu\u00e9es essentiellement de coquilles siliceuses fossilis\u00e9es d’algues unicellulaires microoscopiques, et sont utilis\u00e9es comme auxiliaires de filtration en raison de leur porosit\u00e9 et de leur grande capacit\u00e9 d’adsorption.<\/p>\n
En raison de sa grande porosit\u00e9, la diatomite extraite des carri\u00e8res contient 60 \u00e0 70 % d’eau. Apr\u00e8s le broyage, le minerai est s\u00e9ch\u00e9, broy\u00e9 puis purifi\u00e9 sous forme de poudre.<\/p>\n
Les diatom\u00e9es Radifil RW sont ensuite calcin\u00e9es dans des fours \u00e0 800 \u00e0 1100o C. Cette calcination \u00e9limine la mati\u00e8re organique et agglom\u00e8re les diatom\u00e9es, sans alt\u00e9rer leur porosit\u00e9.<\/p>\n
Apr\u00e8s refroidissement, le produit est broy\u00e9 puis tri\u00e9 afin de r\u00e9aliser des coupes granulom\u00e9triques pr\u00e9cises, r\u00e9pondant aux diff\u00e9rentes applications.<\/p>\n
