Hose delivery for pneumatic conveying dry substances abrasive. special The design hose o exceptional resistance to abrasion. Layer inner smooth, with black antistatic rubber natural with embedded in it balls with corundum (Al 2 O 3 – oxide aluminum), material ceramic o high hardness. built-in cable copper, which po earthing (connection with earthed fitting) discharges charges electrical. Layer outer with black, antistatic (R 6 Ω) rubber SBR / NR resistant to abrasion and aging. hose intended for conveying dry strong abrasive substances: e.g. dry cement, carbon, dust carbon, coke, solid fuels with raw materials secondary, minerals, powders ceramic, shot steel, fragments glass, fibre glass. used in smelters, coking plants, power plants, cement plants, mines, smelters glass, factories materials abrasive and materials insulating. advantage is large service life hose in these use – traditional hose with rubber resistant to abrasion can work e.g. only several dni, a hose ALUSPHERE in these same conditions even several months. Inner layer: balls ceramic embedded in black rubber NR. Reinforcement: cord synthetic. Outer layer: black rubber SBR/NR. Working pressure: 12 bar. Operating temperature: od -30°C up to +80°C.
