Introduction of White Carbon Black Materials
White carbon black is a general term for white powder X-ray amorphous silicate and silicate products. It mainly refers to the precipitation of Silicon dioxide, gas phase silica, ultra-fine silica gel and Aerogel, and also includes powdered synthetic aluminum silicate. And calcium silicate. White carbon black is a porous substance and its composition can be represented by SiO2 · nH2O, where nH2O is in the form of a surface hydroxyl group. Soluble in caustic soda and hydrofluoric acid, insoluble in water, solvents and acids(except hydrofluoric acid). High temperature, non-flammable, tasteless, odorless, with good electrical insulation.

operating principle
Hot air from the inlet pipe enters the mixing and crushing drying chamber from the bottom of the dryer at an appropriate spray speed, and has a strong shear, blowing, and rotation effect on the material, so that the material is atomized by centrifugation, shear, collision, and friction. Enhanced mass transfer heat transfer. At the bottom of the dryer, larger, wetter particles are mechanically broken under the action of a blender, and particles with lower wet content and smaller particles are clamped up by a rotating air stream and further dried during the ascent. Due to the gas-solid two-phase rotation flow. The solid phase inertia is greater than the gas phase, and the relative velocity of the solid phase is relatively large, strengthening the mass transfer heat transfer between the two phases. Therefore, the machine has a high production strength.
