High Speed Dryer

Detailed Product Description

Working Principle:
XSG series rotary flash dryer is a high efficient new type drying equipment with wide accommodation developed and designed on the basis of summarizing the vulcanizing bed, thermal smashing, rotational flow and grading technology. The heated (or dehumidified) air enters into the agitating breaking drying chamber from the bottom of the dryer with a suitable spouting speed to produce a strong cutting, blowing and floating and rotating function to the materials, and then the materials are centrifuged, cut, impacted and rubbed to become micronized, forming larger specific surface area and strengthening the heat transmission of the mass transfer. The large and wet pellet groups are smashed under the action of the agitator at the bottom of the drying chamber and the smaller pellets with less moisture content are brought up by the rotating air flow, dried further during going up and graded.

Characteristics
Drying sticky materials
The cone structure in the dryer, washing out of the air flow to the wall and the structure of the agitator determines it can deal with certain sticky materials.
Drying thermo-sensitive materials
As the drying time is short, the relative speed between the materials and the hot air is big, and the hottest air does not contact the dried materials directly, it is suitable to treat the thermo-sensitive materials.
The drying intensity is high.
As the materials are smashed, washed out and impacted, its surface area increases and the drying is strengthened; At the same time, as the hottest air does not contact the dried material directly, the entering air temperature can be made higher than the melting point of the materials, therefore, the drying intensity of the equipment is high
Efficiently control the final moisture and fineness
The final moisture and the fineness of the finished product is effectively controlled by the internal devices equipped in the drying tower (swirl-flow flake, elutriate ring or grader) , and the coordination with the temperatures of the entering and discharging air.
Environment meets the standards.
The system eliminates the operation environment pollution under the negative pressure in the operation and it adopts different dust removing mode and materials according to the different raw materials (pulse bag dust catcher, water shower duster, Venturi damp dust remover and so on).
Low labor intensity
The feeder and the discharger are made in different forms according to the difference of the materials so as to reach automatically continuously feeding and discharging aims.
The best power matching
The blower, the draught fan, the agitator and the feeder and so on are furnished with the best power according to the different nature of the materials (density, bulk density, viscosity, fineness, primary moisture, final moisture, angle of repose and so on).
