The hot air tangentially enters the bottom of the dryer and forms a strong rotating wind field driven by the stirrer. The paste material enters the dryer by the screw feeder. Under the strong action of the high-speed rotating stirring paddle, the material is dispersed under the action of impact, friction and shear stress, and the block material is quickly crushed, fully in contact with the hot air, heated and dried. The dehydrated dry material rises with the hot air flow, the grading ring traps the large material, the small particles are discharged from the center of the ring outside the dryer, and are recovered by the cyclone separator and dust collector. The dry or large material is thrown to the wall by the centrifugal force and falls to the bottom again to be crushed and dried.
Scope of application
The device is suitable for drying filter cake, paste, slurry, powder and granular materials.
Widely used in mineral, chemical, light industry, food, medicine and other industries. Such as: barium carbonate, cyanuric acid, light calcium carbonate, dyes, kaolin, vanadium pentoxide, zinc sulfate, calcium hydrogen phosphate, active zinc oxide, white gray black, aureomycin, magnetic materials and alumina.
Product characteristics
1) High drying strength, suitable for paste and cake drying;
2) The equipment is small, and the volume of the spray drying equipment is about 1/4 of the same production capacity;
3) Short drying time, especially suitable for heat-sensitive materials;
4) The equipment body has no sticky wall phenomenon;
5) Compared with the box-type drying method, it does not need to be crushed after drying, which can save 30~50% energy;
6) Closed operation, no pollution to the environment.
7) The organic combination of swirl, fluidization, spray and grinding classification technology.
