Basalt granite white gravel

Basalt is a type of volcanic eruption rock primarily used for the production of cast stone and rock wool or fibers. The color is generally gray black, some are green, gray green, and dark purple. The structure is commonly patchy, with a few being unblemished fine-grained structures. Constructed as a dense block structure, it often has a porous structure, almond shaped structure, and hexagonal columnar joints. The mineral composition is mainly composed of olivine, basic plagioclase and other minerals, with a fine-grained base, sometimes cryptocrystalline or semi crystalline, composed of microcrystals and glassy materials. The application field is ① Cast stone PRODUCTS: using basalt as the main raw material, adding pyrite, amphibole, dolomite, fluorite, etc. to make cast stone PRODUCTS. This product has high chemical corrosion resistance, wear resistance, and high hardness and mechanical strength, and can be widely used in industrial sectors such as chemical, metallurgical, power, building materials, construction, light industry, coal, textile, etc. Rock wool PRODUCTS: Rock wool PRODUCTS made mainly from basalt and added with dolomite, slag, etc. are a new type of lightweight insulation material with good insulation, thermal insulation, and sound absorption properties. The chemical properties are stable and have the characteristics of heat resistance and non flammability. Basalt fiber: Continuous basalt fiber prepared from basalt as the main raw material is a high-performance mineral fiber material with stable chemical properties, high strength, sound insulation, heat insulation, fire resistance and flame retardancy. Widely used in fiber-reinforced composite materials, friction materials, shipbuilding materials, insulation materials, automotive industry, high-temperature filter fabrics, and environmental protection fields.
