Overview of Rotary Flash Dryer Equipment:
The flash dryer (also known as rotary flash dryer or instant dryer) is a high - efficiency and continuous drying equipment, specifically designed for processing difficult - to - dry materials such as pastes, filter cakes and high - viscosity liquids.
The flash dryer cleverly combines fluidized bed, pneumatic drying and crushing technologies. Its core working principle is as follows: The wet materials are fed into the bottom of the drying chamber, where they meet the high - speed rotating crushing agitator at the bottom and are instantly dispersed and crushed. Meanwhile, the high - temperature hot air rising at high speed (usually 400 - 700°C) is fully mixed with these dispersed tiny wet material particles. The materials are suspended, fluidized and complete the heat and mass transfer process in a very short time (usually from a few seconds to dozens of seconds), and the moisture is rapidly evaporated. The dried fine powder enters the cyclone separator and bag filter with the airflow for collection, and the tail gas is discharged.
This "bottom crushing + instantaneous convection of hot air" mode enables it to effectively solve the drying problems of high - humidity and high - viscosity materials.
The flash dryer plays a core role in the post - treatment drying process of titanium dioxide (TiO₂). It is the mainstream drying equipment for large - scale production in the current industry.
The production of titanium dioxide is mainly divided into the sulfuric acid method and the chlorination method. Regardless of the method, the drying of wet materials (filter cakes or slurries) is a key link in the quality control of the finished products. Due to its unique working principle, the flash dryer perfectly meets the strict requirements of titanium dioxide drying.

Main Advantages and Features of Flash Dryer:
Unique Advantages in Processing Materials
No pre - treatment required: It can directly process high - viscosity and high - moisture materials such as pastes, filter cakes and slurries, eliminating the cumbersome pre - treatment processes such as dilution and granulation.
"One-step" drying: Integrates drying, crushing, and screening. During the drying process, the materials are continuously crushed and classified by the bottom crushing device and high-speed airflow, and finally uniform fine particle products are obtained.
High efficiency and energy saving
High drying intensity: Since the materials are highly dispersed and have a huge contact area with the high-temperature hot air, the heat and mass transfer rates are extremely fast, and the evaporation capacity per unit volume is large.
High thermal efficiency: The high-temperature gas is in co-current contact with the wet materials. The temperature difference at the inlet is large, the power consumption is relatively low, and the comprehensive thermal efficiency is high.
Good product quality
Controllable temperature, suitable for heat-sensitive materials: Although the inlet air temperature is very high, due to the rapid evaporation of the moisture in the materials which takes away a large amount of heat and the extremely short residence time, the actual temperature of the materials is much lower than the outlet air temperature, which can effectively avoid overheating and denaturation of the materials and maintain their activity.
Uniform product particle size and good fluidity: By adjusting the speed of the crusher and the air volume, the particle size and moisture of the final product can be controlled.
Convenient operation and control
Continuous automated production: It can realize the whole-process continuous automated operation from feeding, drying to powder collection, which is suitable for large-scale industrial production.
Negative pressure operation of the system: The whole system operates under a slight negative pressure state. The dust is not easy to escape, the working environment is clean, and the safety is high.
Compact structure and relatively convenient maintenance
The main body of the equipment is a vertical structure, which covers a small area.
-
The main moving part is the crushing agitator at the bottom. The structure is relatively simple, and the maintenance points are concentrated.
Typical application fields of flash dryer:
Inorganic chemicals:Calcium carbonate, kaolin, silica, aluminum hydroxide, various metal hydroxides, pigments, catalysts, etc.
Organic chemicals:Dyes, pigment intermediates, pesticides (such as glyphosate), flame retardants, resins, etc.
Minerals and metallurgy: Ceramic raw materials, bentonite, various metal ore powders, sludge, etc.
Food and feed:Starch, soy protein, corn syrup, yeast, distillers' grains, etc. (food-grade configuration and heat source are required).
