With the process of removing sand and impurity, crashing, filtrating, vermiculites become exfoliated, they can be divided into different sizes: 0-1mm, 1-2mm, 2-4mm, 1-3.5mm, 3-5mm, 4-6mm and so on, we can produce many sizes as clients required. There are two kinds of vermiculite in our country golden vermiculite and silvery vermiculite, they have different chemical components. Main applications: 1.construction materials: light materials such as light concrete materials, light calcimine and light mortar. 2. heat resisting material: wall materials, anti-fire board, anti-fire mortar, firebrick, and brake linings. 3. heat preservation, thermal insulation and sound absorption materials: underground pipeline, heat preservation material used in hothouse pipeline, decoration material used in upholstery and tunnel, also wall and ceiling in the public. 4.metallurgy: steel frame cladding materials, removal of slag when manufacture of iron and foundry 5. agriculture, forestry and horticulture: golf course lawn, seed preservation agent, soil regulation agent, wetting agent, plant growth agent, feed additives, horticulture mixture, fishing and bait. 6 other aspects: adsorptive material, filter aid, active carrier of chemical and chemical fertilizer, sewage treatment, adsorption of seawater oil pollution, cigarettes filter and explosive density regulators.
