White carbon black material introduction
White carbon black is a general term for the white powder X-ray amorphous silicic acid and silicate products, mainly referring to precipitated silica, fumed silica, ultrafine silica gel and airgel, Synthetic aluminum silicate and calcium silicate. Silica is a porous material whose composition is represented by SiO2 · nH2O, where nH2O is present as a surface hydroxyl group. Soluble in caustic and hydrofluoric acid, insoluble in water, solvents and acids (except hydrofluoric acid). High temperature, noncombustible, tasteless, odorless, with good electrical insulation.
working principle
Hot air from the inlet pipe at a suitable spouting speed from the bottom of the dryer into the mixing crushing drying chamber, the material has a strong shear, blowing, rotating role, so the material by centrifugal, shear, collision, friction and be micronized , Enhanced mass and heat transfer. At the bottom of the drier, the larger and more wet granulation is mechanically crushed by the agitator. The lower the moisture content, the smaller granularity is entrained by the rotating airstream and further dried during ascent. Due to the gas-solid two-phase rotation flow. The inertia of the solid phase is larger than that of the gas phase, and the relative velocity between solid and gas phases is larger, which enhances mass transfer and heat transfer between the two phases. Therefore, the production of high strength machine.
