The three cylinder dryer has a compact structure, simple construction, reasonable layout, improves the heat exchange rate between materials and heat energy, reliable operation, low energy consumption, and high thermal efficiency;

　　Main features

　　1. High technical content, self insulation of the cylinder body, thermal efficiency up to 80% (the thermal efficiency of a single cylinder dryer is only 35%), saving 68% of coal compared to single cylinder drying, and increasing production by 100%.

　　2. Shortening the overall length of a single drum dryer by 60% is beneficial for process layout. Reduce the building area of the factory and save about 40% of the project investment. Covering an area of approximately 20m2.

　　3. Made of heat-resistant and wear-resistant alloy steel plate, which is four times more wear-resistant than ordinary steel plate. Long service life and easy maintenance.

　　4. High thermal efficiency, outer cylinder temperature below 60 ℃ (single drum dryer outer cylinder temperature up to 150 ℃), low outlet temperature, and discharge temperature below 60 ℃.

　　5. Low export temperature is beneficial for extending the service life of dust removal equipment, and can be directly matched with gas box pulse bag filter.

　　6. Hot blast stove can be matched with boiling furnace, coal injection furnace, and gas furnace.
