Introduction of white carbon material
Silica is the general term for white powder X-ray amorphous silicic acid and silicate products, mainly refers to precipitated silica, fumed silica, ultrafine silica gel and airgel, as well as powdered Synthetic aluminum silicate and calcium silicate. White carbon black is a porous material, its composition can be expressed as SiO2 · nH2O, where nH2O is in the form of surface hydroxyl. Soluble in caustic and hydrofluoric acid, insoluble in water, solvents and acids (except hydrofluoric acid). High temperature, nonflammable, tasteless, odorless, with good electrical insulation.
working principle
Hot air from the inlet tube at the appropriate spray speed from the bottom of the dryer into the mixing crushing drying room, the material produced a strong shear, blowing, rotating, so the material by centrifugation, shear, collision, friction and micro-granulation , Enhanced mass transfer heat transfer. At the bottom of the dryer, the larger and heavier particles are mechanically crushed under the action of a stirrer, the moisture content is low, and the particles with smaller particle size are entrained by the rotating air stream and are further dried during the ascending process. As the gas-solid two-phase rotation flow. Solid phase inertia is greater than the gas phase, the relative speed between the two phases of solid gas is relatively large, and the heat transfer between the two phases is enhanced. So the machine production strength is high.
