Silk long basalt material ?? ?? heavy (kg / m2) 8.0 thick ?? degree (mm) 5.0 through? Gas? Volume (m3 / m2.min) 3.0 Tensile strength (kg / 40mm)> 600 Temperature 300 ℃ -800 ℃ characteristics: clear, smooth, dimensionally stable, no deformation. Airflow uniform and stable. Heat-resistant, corrosion-resistant. Low energy consumption, long life, minimal amount of maintenance. Basalt filament as raw material, good wear resistance, tensile strength, use of high temperature. Uses: The product is mainly used as an air funnel silo chute and accessory products for the delivery of dry powder materials. Widely used in cement, thermal power plants, alumina,? Horizontal conveyor and silo alumina, soda ash, gypsum, flour and other industries boil.
