| Brief Introduction For the 3 pass rotary dryer |
Raw material with 10-25% moisture content is suitable for this dryer,and not sticky for the drum or lifting blade. The temperature of air flow is less than 70 degree. When there is any special requirement for high temperature drying, the front part of inner drum and lifting blade could be replaced by heatproof steel plate. The product moisture content is adjustable according different requests, even below 1-0.5%. | ||
Applications |
industrial small silica sand triple pass rotary drum dryer used rotary sand dryer price used for drying certain humidity range granular materials, such as 1.casting sand which used in dry-mixed mortar and foundry industry 2.small granular clay used in construction and cement industry 3.small granular material in chemical industry which no chemical change, not afraid of heat and dust pollution such as coal, blue carbon, fly ash, sand, water slag, river sand, quartz sand, slag, clay etc. |

Features of the 3 pass rotary dryer |
1.The dryer drum made of wear resistant manganese plate, service life 3-4 times than common steel plate | ||
| 2.Original moisture contains <15%, after drying final moisture contain 0.5-1%. First choice for cement slag powder, pre-mixed mortar projects. | |||
| 3. The thermal efficiency is more than 40% higher than that of traditional single drum dryer | |||
| 4. Fuel applicable white coal, bituminous coal, coal gangue, oil, steam. Raw material required <40 mm bulk, aggregate, powder material | |||
| 5.reduce 60% working place, 60% civil work compare with normal single drum dryer. Easy operation. | |||
| 6.No air leakage phenomenon, solved the sealing problem. | |||
| 7.discharge temperature <60 ºC,could storage directly in the silo, no need cooling section. | |||
| 8. Outer barrel temperature <60 ºC, the exhaust gas temperature < 120 ºC, dust removal equipment could serve 2 times longer. | |||
| 9.reduce 2/3 coal, 40% electric consumption. Need <9kg coal to dry one-ton raw material | |||

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.
