Pigment is a substance that gives color to an object. Pigments are soluble and insoluble, inorganic and organic. Inorganic pigments are generally mineral substances, and humans have long known the use of inorganic pigments, the use of colored soil and ores, to paint and paint the body on the rock wall. Organic pigments are generally derived from plants and Marine animals, such as cyanoblue, garcinia, and purple extracted from shellfish in ancient Rome. Pigment is a colored fine particle powder substance, generally insoluble in water, can be dispersed in various, oil, solvent and resin and other media. It has covering power, coloring power, relatively stable to light, and is often used to prepare paints, inks, and coloring plastics and rubber, so it can also be called coloring agent.

Iron oxide, alias iron trioxide, burnt limonite, burnt ochre, iron Dan, iron red, red powder, Venice red (the main component of iron oxide) and so on. The chemical formula Fe2O3, dissolved in hydrochloric acid, is a reddish brown powder. Its red-brown powder is a low-grade pigment, called iron oxide red in industry, used in paint, ink, rubber and other industries, can be used as a catalyst, glass, gems, metal polishing agent, can be used as iron making raw materials.

Flash dryer (iron oxide red dryer, iron oxide red dryer) is a new type of continuous drying equipment that integrates drying, crushing and screening, especially suitable for the drying of filter cake, paste and mud paste. Heater, feeder, stirring crushing system, classifier, drying main, cyclone separator, bag dust collector, fan, etc.

The hot air enters the annular gap at the bottom of the drying chamber in the tangential direction from the inlet pipe and rises spirally. At the same time, the material is quantitatively added into the tower by the feeder and has full heat exchange with the hot air. The large and wet material is mechanically broken under the action of the agitator, and the material with low wet content and small particle size rises with the rotating air flow and is transported to the separator for gas-solid separation. The finished product is collected and packaged, while the exhaust gas is treated by a dust removal device and emptied.

1. The drying room has high circumference-based gas velocity and short material residence time, which effectively prevents the material from sticking to the wall and the deterioration of heat-sensitive materials, and can be dried into uniform powder products at one time, eliminating the grinding and screening processes.

2. The drying chamber is equipped with grading ring and swirl sheet, material fineness and final moisture can be adjusted. The special air distribution device reduces the resistance of the equipment and effectively improves the drying uniformity of the material.

3. The bottom of the dryer is equipped with a special cooling device and air pressure seal to avoid the deterioration of the material in the bottom high temperature area.

4. Can effectively control the final moisture and fineness, through the feeding, hot air temperature, classifier adjustment, to ensure that the product moisture content and fineness uniform.
