Advanced Technology Triple Pass Rotary Drum Dryer For Silicasand/Sawdust
Advanced Technology Triple Pass Rotary Drum Dryer For Silicasand ,Sawdust
triple pass rotary drum dryer Processed Materials:River sand, artificial sand, silica sand, yellow sand, mineral sand, mineral powder, slag, coal ash, coal slag, etc.
Application: Dry-mixed mortar industry, cement, building materials, glass, foundry industry, chemical industry, etc. triple ppass rotary drum dryer has compact structure and covers a small area which is half of the single drum dryer does. The three-drum dryer works reliably with low energy consumption and high heat efficiency which realizes good material drying effect, simple automation control and few operating staff.
Capacity:1-50tones per hour
Heating Fuel:Coal, Gas, Oil, Biomass fuels, Wood,etc
Based on single pass drum dryer, Hengxing equipment also develop triple pass drum dryer to take drum drying technology a step further. Triple pass rotary dryer improves the performance in operation cost, service life, energy efficiency, product consistency.
Triple pass rotary drum dryer has proved its application in building materials, chemical, foundry, cement industry. It is used in the dehydration of dry mixed mortar, silica sand, foundry sand, iron powder, coal gangue, blast furnace slag, fine clay, etc. Final moisture content could be reduced to 0.5-1%. Optimal feeding particles should be below 30mm.
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.
As three passes are concentric and interlocked, full-length drums maximize the effective length and residence time in a much smaller floor area compared with single pass dryer. Instead of gear driving or chain driving, triple pass drum dryer is driven by the rollers. Smooth transmission reduces abrasion and extends service life.
Triple pass rotary drum dryer working principle :
Materials enter the inner side of the drum through the feeding device to realize current flow drying process, then the materials enter the middle layer of the inner wall through the other end to realize counter current drying process. They are lifted in over and over in the middle layer which advance in two-steps forward and one-step back way. The three-drum dryers absorb heat from both inner drum and middle drum, which extend the drying time and realize the best drying condition. Finally, materials fall into the external layer of the drum from the other end of the middle layer, processing in a rectangle multi-loop way. The dried materials move quickly out of the drum under the hot air, while the wet ones remain because of their own weight. Materials are dried completely inside the rectangle shoveling plate and then cooled by the single drum cooler, thus finishing the whole drying process.
Advantages of triple pass rotary drum 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.
