Sand Dryer Description:
Sand dryer is a sort of dryer that can handle a large amount of materials.Owing to the reliable operation,flexible manipulation,large capacity,excellent adaptation of the machine,this sand dryer is widely used in construction industry,metallurgical industry,mining industry,food industry etc.

Silica Sand Dryer Advantages:

1.High technical content, self insulation cylinder body, 80% thermal efficiency (single- cylinder dryer is only 35%), coal saving is 68% than single-cylinder dryer and output increases 100%
2. The length is good for technical layout, 60% shorter than single-cylinder dryer. Also it’s about 20m³area, reducing plant area and saving 40% investment

3.Adopt heat resistant and wear resistant steel plate, 4 times wear resistant than the general steel plate, long service time and convenient to maintain.

4. outside cylinder body temperature is below 60°(single cylinder temperature is up to 150°), with low outlet temperature.

5.low outlet temperature is good for keeping long service life.

6.electic consumption reduce 60%

7.adopt roller rotation, without large and small gear

Silica Sand Dryer Working Principle:
sand dryer adopts direct flow type of heating with heat source from firing uint. The material to be dried is pushed back immediately by spiral board when enters the shell from feeding tank and feeding chute. Because the Rotary Dryer is installed in slope, material flows to the back end under gravity and rotation force, meanwhile, the Rotary Dryer lifted by board repeatedly and thrown down accordingly, which make the material from even curtain and exchange heat sufficiently with inner the heat flow. In the end, water in the material is dried by repeatedly scattering.
