Product Specification

White carbon black introduction:

White carbon black is a general term for white powdered X-ray amorphous silicic acid and silicate products, mainly precipitated silica, fumed silica and ultrafine silica gel, and also includes powdered synthetic aluminum silicate and calcium silicate. White carbon black is a porous substance, and its composition can be expressed by SiO2·nH2O, where nH2O exists in the form of surface hydroxyl groups. It is soluble in caustic alkali and hydrofluoric acid, insoluble in water, solvents and acids (except hydrofluoric acid). It is resistant to high temperatures, non-flammable, tasteless, odorless, and has good electrical insulation.

Working principle:
Hot air enters the bottom of the dryer tangentially, and forms a strong rotating wind field driven by the agitator. Paste materials enter the dryer from the spiral feeder. Under the strong action of the high-speed rotating agitator, the materials are dispersed by impact, friction and shear force, and the block materials are quickly crushed, fully contacted with the hot air, heated and dried. The dehydrated dry materials rise with the hot air flow, and the classification ring intercepts the large particles. The small particles are discharged from the center of the ring and recovered by the cyclone separator and dust collector. The undried or large pieces of materials are thrown to the wall of the device by centrifugal force and fall to the bottom again to be crushed and dried.

Performance characteristics:
◎Organic combination of swirl, fluidization, spraying and crushing and classification technology.
◎Compact equipment, small size, high production efficiency, continuous production, realizing "small equipment, large production".
◎High drying intensity, low energy consumption and high thermal efficiency.
◎Short material residence time, good finished product quality, can be used for drying heat-sensitive materials.
◎ Negative pressure or micro-negative pressure operation, good airtightness, high efficiency, and elimination of environmental pollution.

Technical specification:

Note: 1. The amount of water evaporation is 180OC in the air inlet, and the water evaporates every hour when the air temperature is 80℃.

2. Except for the above models, you can make special designs for users.

3. The above installation capacity is a standard support, which can be significantly reduced according to different power facilities.
