Types:
1.Dried products: After the raw diatomite being drying under 100℃~300℃, and then pulverization purified by high pressure gas flow, the product can be produce by classification, and it turns to be gray white or light yellow.
2. Roasted products: the product is produced and roasted after refined diatomite under high temperature 800℃~900℃. With high pressure gas folw pulverization and classfication, it turns to be reddish ornage.
3. Aided-melting roasted products: the cleaned diatomite is mixed with proper amounts of melting additive and roasted after refined ones under 900℃~1200℃, pulvweization and calssfication, it turns to be white.
