Three-drum Dryer

Three-drum dryer or triple drum dryer isdeveloped on the basis of German advanced technology and combined by three concentric cylinders with different diameters according to certain mathematical relationship and structure form. Its cylinder lengthen is about 1/3 of single cylinder dryer and covering area about 65% less than the latter, which can savethe infrastructure investment a lot. The dryer is driven by the friction between riding wheel and tyre, which requires low transmission power and produces less noise when working.

The sealing system adopts micro contact technology which has a better sealing effect and produces less powder dust pollution. The three-cylinder dryer can be fueled by many kinds of energy like coal, oil and gas etc, and suitable for all kinds of materials with block shape, granular shape and powder shape. The three drum drying machine is an alternativeto traditional drying equipment, because it conforms to the national policy of creating an environment-friendly and resource-conserving society.

Features of Three-cylinder Dryer

1. The cylinder is advanced in technology and can preserve heat by itself. Its thermal efficiency can reach 80% in thermal efficiency(35% for single cylinder dryer), 68% in coal saving and 100% production improvement than the single cylinder dryer.

2. The whole length is 60% shorterthan single cylinder dryer, which creates great convenience to process layout and building area reduction (the covering area of three-cylinder dryer is about20m2). 40% of the project investment can be saved.

3. The three-cylinder dryer adopts the heat resistant and wear resistant alloy steel plate which is 4 times stronger than the common steel plate. So it is longer in service life and easier to repair.

4. The thermal efficiency is high. The temperature of outer cylinder is below 60℃ (that of single drumdryer can reach 150℃). The discharging area and final materials also have a low temperature—below 60℃.

5. The low temperature of discharging area can prolong its service life and can be equipped with the pulsed baghose precipitator with air box directly.

6. It can reduce about 50% building investment and 60% electricity consumption.

7. It is driven by the riding wheel, needing no big and small gears.

8. The hot stove can be equippedwith furnace in fluid bed, coal spraying stove, hand stove, oil stove and gasstove and suitable for block, granular and powder shaped materials smaller than 20mm.
