Three-cylinder dryer is mainly applied for stoving slag, sand, coal, fly ash, iron powder, ore, quartz sand and other particle materials.
Three-cylinder dryer is mainly applied for stoving slag, sand, coal, fly ash, iron powder, ore, quartz sand and other particle materials, with following characteristics:
1. Self-cylinder insulation, thermal efficiency up to 95%.
2. The whole length of the dryer than mono-cylinder reduced by about 50%, by this bringing down land investment.
3. Cylinder applies heat-resistant and wear-resistant steel plate welding, with long service life and easy maintenance.
4. With high thermal efficiency, temperature of outer cylinder is not more than 60℃ (temperature of outer mono-cylinder is high to 150℃ ).
5. Low outlet temperature, long-service dust removal, can be directly connected to air box pulse bag filter.
6. Without gear and pinion drive, but wheel rotation applied, level operation of the complete machine makes system simple and reasonable.
7. Airheater could match boiling furnace, or oil furnace and gas furnace can also be applied, which can dry materials with size below 20mm.
8. Final moisture can be adjusted according to requirement of customer.
