The pressure atomizer spray drying machine will compress the feeding material into the nozzle atomizer on top of the drying tower, so that the material will be atomized into tiny fog-drops. They will fall down from the top of the tower along with hot air so that it can be dried. Thus, the slurry with higher solid content can be atomized and granulated by pressure. Then it will be dried to form spherical particles. The dried product features good free fluidity.
The centrifugal spray dryer has three kinds of structural layout:
Conventional Spray Dryer
Versatile Spray Dryer, Single Point Discharge
Versatile Spray Dryer, Two Point Discharge
The atomizer of this centrifugal spray dryer adopts SKF bearing imported from Sweden. The unloaded vibration value of this kind of bearing is smaller than 5um. And the loaded vibration is less than 15um. The whole dryer can run up to 7000h without failures. It can also be equipped with additional vibration system which can be used to clean the powder on the inner wall of the dryer via vibration. The powder can also be cleaned by air sweeper.
The following are some kinds of commonly used centrifugal spray dryer for you to choose from, you can also make some related improvements on the base of various types:| Type Item |
