Three Cyclinder Rotary Sand Dryer Use Coal Fuel And Gas Fuel
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.
» Applications: Various sand: eg. River sand, sea sand, mining sand, molding sand,
etc. |
| Grain sizes: 0.075 to 10mm typically |  |
» Output Capacity: 3 t/h to 10 t/h Final moisture: ≤ 0.5% |
» Motor Power: 4 Kw/h to 88 Kw/h |
» Drying Temperature: Max. 750 oC |
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.
Technical Parameters of widely used rotary sand dryer:
| Model | Capacity | Moisture of finished drying sand | Coal burning capacity(kg/t) | Sand dryer main motor (kw) |
| MG623 | 3-5t/h | <0.5% | 16-18 | 4 |
| MG625 | 5-8t/h | <0.5% | 15-17 | 5.5 |
| MG6210 | 10-12t/h | <0.5% | 14-16 | 8 |
