Pigment (iron oxide) dedicated flash dryer
Detailed description
Pigment (iron oxide) dedicated flash dryer
project description:
Pigment infected object is to make the color of the
material. Pigments soluble and non-soluble, inorganic and organic
difference. Inorganic pigments are generally mineral substances, humans
have long known that the use of inorganic pigments, the use of colored
soil and minerals, body painting and painting on the wall. Organic
pigments are generally derived from plants and marine animals, such as
Qian blue, Garcinia and Roman purple extracted from shellfish. Colored
pigment is a fine particle powder-like substance is generally insoluble
in water, can be dispersed in various, oils, solvents and resins other
media. It hiding power, tinting strength, is relatively stable to light,
commonly used in the preparation of coatings, inks, and colored plastic
and rubber, it can be said that the colorant.
Material Overview:
Iron oxide, ferric oxide alias, limonite burning, burnt
ocher, iron oxide, iron oxide red, Pink, Venetian Red (mainly composed
of iron oxide) and the like. Chemical formula Fe2O3, was dissolved in
hydrochloric acid as a reddish brown powder. Its reddish brown powder is
a lower pigment called red iron oxide, used in paint, ink, rubber and
other industries, do catalyst, glass, stones, metal polishing agent,
used as iron raw material industry.
Equipment summary:
Flash dryer (iron oxide red dryer, iron oxide red dryer)
is a dried, pulverized and sieved in one of the new continuous drying
equipment, especially for the cake-like, paste, mud slurries
drying. Heater, feeder, stirring crushing system, classifier, drying
competent, cyclone separator, bag filter, fan and other components.
How it works:
Hot air inlet tube tangentially into the bottom of the drying chamber annulus, and a spiral rise, while the material from the feeder metered into the tower, and with hot air heat exchange sufficiently larger than the wet material under the action of the agitator is mechanically crushed, low moisture content and smaller particle size of the material rise along with rotating air stream delivered to the separator gas-solid separation, product packaging and collection, and the exhaust after treatment devices dust emptying .
Hot air inlet tube tangentially into the bottom of the drying chamber annulus, and a spiral rise, while the material from the feeder metered into the tower, and with hot air heat exchange sufficiently larger than the wet material under the action of the agitator is mechanically crushed, low moisture content and smaller particle size of the material rise along with rotating air stream delivered to the separator gas-solid separation, product packaging and collection, and the exhaust after treatment devices dust emptying .

Features:
1, the gas inside the drying chamber to the high-speed, short
residence time, effectively prevent the wall material viscosity and
heat-sensitive materials deterioration, and once dried into a uniform
powder products, eliminating the need for crushing, screening and other
processes.
2, the drying chamber is equipped with grading ring and swirl sheet
material fineness and final moisture adjustable. Special air
distribution system, reducing the resistance of the device, and
effectively improve the uniformity of dried material.
3, the bottom of the dryer to set a special cooling device and
pneumatic sealing device to avoid material deterioration phenomenon
generated at the bottom of the high temperature zone.
4, can effectively control the final moisture and fineness, by
feeding hot air temperature, the classifier is adjusted to ensure that
the moisture content and product fineness uniform.
