Introduction of silica materials
Silica is a white powder X-ray amorphous silicic acid and silicate products in general, mainly refers to the precipitated silica, fumed silica, ultrafine silica gel and aerogels, including powder Synthetic aluminum silicate and calcium silicate. White carbon black is a porous material, its composition can be SiO2 · nH2O said, which nH2O is the surface hydroxyl form. Soluble in caustic and hydrofluoric acid, insoluble in water, solvents and acids (except hydrofluoric acid). High temperature, non-flammable, tasteless, odorless, has a good electrical insulation.

Working principle
Hot air from the inlet pipe at the appropriate speed from the bottom of the dryer into the mixing crushing chamber, the material has a strong shear, blowing floating, rotating role, so the material by centrifugation, shear, collision, friction and micronized , Enhanced heat and mass transfer. At the bottom of the dryer, the larger, wetter particles are mechanically broken by the agitator. The particles with low moisture content are entrained by the rotating airflow and are further dried during the rising process. Due to gas-solid two-phase rotation flow. Solid phase inertia is greater than gas phase, solid-gas two-phase relative velocity is bigger, strengthen two-phase mass transfer heat transfer. So the aircraft production of high strength.
