Professional manufacturer of bentonite rotary flash dryers, high-efficiency and energy-saving bentonite drying machine.

Professionally providing various types of flash drying equipment, supplying a specialized rotary flash dryer for bentonite.

Working Principle of Bentonite Flash Dryer:

Hot air enters tangentially at the bottom of the dryer, forming a powerful rotating airflow driven by the agitator. Bentonite is fed into the dryer via a screw feeder. Under the intense action of the high-speed rotating stirring blades, the bentonite is dispersed through impacts, friction, and shear forces. The lumpy bentonite is rapidly crushed, fully contacting the hot air, being heated, and dried. The dehydrated dry material rises with the hot airflow, where the classification ring retains large particles, while small particles exit the dryer from the center of the ring and are recovered by a cyclone separator and dust collector. Incompletely dried or large materials are thrown toward the wall by centrifugal force, falling back to the bottom to be crushed and dried again.

Performance Characteristics of Bentonite Flash Drying Equipment:

The organic integration of swirling, fluidization, spouting, and crushing-classification technologies. The equipment is compact, small in size, with high production efficiency and continuous operation, achieving "small equipment, large output." It features high drying intensity, low energy consumption, and high thermal efficiency. The material residence time is short, ensuring good product quality, and it can be used for drying heat-sensitive materials. It operates under negative or slight negative pressure, with excellent sealing, high efficiency, and elimination of environmental pollution.

Suitable for organic materials:

Atrazine (pesticide insecticide), lead laurate, benzoic acid, benzoin, captan, sodium oxalate, cellulose acetate, organic pigments, and other dyes: anthraquinone, black iron oxide, indigo pigment, butyric acid, titanium hydroxide, zinc sulfide, various azo dye intermediates. Inorganic substances: borax, calcium carbonate, hydroxides, copper sulfate, iron oxide, barium carbonate, antimony trioxide, various metal hydroxides, various heavy metal salts, synthetic cryolite, etc. Food products: soy protein, gelling starch, distiller's grains, wheat sugar, wheat starch, etc.
