GSX spin flash dryer is a new type continuous drying machine with the integration of drying, crashing and classification. It is used for drying filter cake, paste, slurry, powder etc.
Based on our rich enginnering experience and the traditional technology,we improved the transimmision system and the material breaking device and finally improved the drying efficiency and overall performance of the spin flash dryer.
The spin flash dryer system is mainly composed by heating system,feeding system,spin flash dryer,dust collector and drought fan.
The new drying system only uses bag dust collector to separate product,which reduced the system resistance as well as power and energy consumptioin of fans.Working life of filter bags extended by *0%**0% due to the low system resistance.
1. Features:
1) Feed is dried into powder for once,no need regrinding;
suits to filter cake and paste material.
2) Double air duct, tangential air, uniform radical velocity.
3) Continuous operation,stable running,can be PLC automatic control.
4) Final moisture content and fineness can be effectively controlled by coordination of swirl blades and inlet air speed.
5) Special rotary blades distributed structure;
Less abrasion, large interface, stronger cutting force.
6) Suits perfectly to thermal-sensitive material.
7) Short resistance, high thermal efficiency, friendly operating environment.
8) New sealing structure of the drying tower, long bearing life, bearing block with water
circulating jacket cooler.
9) Easy maintenance,long working life.
 Working principle:
Hot air enters into the spin flash dryer tower tangentially from the drying tower bottom, and then forms high-speed spinning air flow in the drying tower. The annulus is adjusted to give an appropriate air speed according to material properties.
Material which is to be dried is fed into the drying tower directly via a screw feeder, then dispersing and spinning in a high speed together with the air flow.
Large-size and wet particles fall down by gravity, and being crashed into tiny particles after falling onto the tower bottom, then rising up rotationally with the high-speed airflow.
Multi-layer swirl blades are installed inside the drying tower to form a stable fluidized bed which guarantees the very low final moisture and avoids the products from being affected by the fluctuation of the initial moisture. Aside from this, the blades can also classify the particles and ensure the required residence time.
Technical advantages:
1) Special designed stucture: the leaned blades are special designed,and distance of the flat blades is larger than common flash dryer. Singles blade can be taken down from the breaking device.Wet raw material can be broken more efficiently by the special rotating blades.
2) Special structure of the classification ring,which garantees the high quality of the product.
3)Special super low pressrue ash-cleaning system,high quality filter bag,large filter area.
4)Dryer thickness: our dryer usually has the thickness of the steel plate 5mm,while other suppliers are **3mm.
5) Large size volute.
6) Big annular space:the annular space is between the air chamber and the drying chamber,big annular space can keep the air in a optimum speed.
