Description of widely used rotary sand dryer:
Rotary Sand Dryers are one of the typical applying area of rotary dryers due to its reliable performance, high efficiency and low manufacturing cost. Our factory has been making rotary dryers for drying sand since 1950s. Back then only single-pass rotary dryers were available for all drying processes. As entering 21st century, all industries facing more and more environmental challenges and higher demand for energy efficiency. Our factory started to R &D Triple-pass Rotary Sand Dryers in 2002, which now has basically replaced conventional single-pass rotary dryer in sand drying plants.

Advantages of widely used rotary sand dryer:
1. With high technical content, cylinder self insulation, thermal efficiency is as high as 80% (single cylinder dryer is only 35 percent), thermal efficiency than single cylinder drying saves coal 68 percent, yields 100%.
2. Compared to single cylinder dryer the machine length shortens 60%, in favour of process arrangement. Reduces workshop covered area, saves the project investment by around 40%. Covers an area of about 20m2.
3. Heat-resisting wear-resisting alloy steel plate, four times than ordinary steel wear-resisting. Long service life and easy maintenance.
4. High thermal efficiency, outside shell temperature below 60 °C (single cylinder dryer outside shell temperature as high as 150°C), output of low temperature, discharging temperature below 60 °C.
5. Output of low temperature, be helpful for dust removal equipment to use a long time, can be directly supporting air tankpulse bag filter.
6. Construction investment reduces 50% or so, power consumption reduces 60%.
7. Don't need sizes of gear-driving,and adopts roller rotation
8. Hot air stove can supporting fluidezed bed, spray stove, hands burned furnace, also used in fuel and gas type, can bake the below 20 mm pieces of materials, aggregates, powder material.
