Three-cylinder Dryer

Working principle
Material from the feeding device into the inner rotary drum and achieve downstream drying, the material in the inner constantly took a copy board, scattered spiral traveling type heat exchange, material movement to the other end of the inner layer into the middle, countercurrent drying, the material is repeated constantly in the middle Yang Jin, was a step back and two steps forward travel mode, both fully absorb the material in the middle inner cylinder the heat, and the middle cylinder to absorb heat, while extending the drying time, the best material in this dry state. Material line to the middle the other end fall into the outer, the material in the outer drum rectangular multi-loop approach road, to reach the drying effect of the material in the hot action fast marching discharge roller, did not reach the drying effect of the wet material and not due to weight fast travel, the material within this rectangle copy board is fully dried, thereby completing the drying purposes.
Main feature
1. equipment investment is required for imported products 1/6.
2. materials final moisture to ensure 0.5% or less, dry-mixed mortar and slag powder production line product of choice.
3. cylinder self-insulation thermal efficiency up to 70% (traditional monocular dryer thermal efficiency of only 35%), to improve the thermal efficiency of 35%.
4. the fuel can be adapted to coal, oil and gas. You can bake 20mm below the block material, pellets and powder materials.
5. than monocular dryer covers an area of about 50% reduction, reduce construction investment is about 50%, power consumption reduced by 60%.
6. according to user requirements easily control the desired final moisture indicators.
7. the outlet temperature is low, dust removal equipment long time.
8. no gear size, the use of wheel drive.
Three drum dryer has a compact, simple structure, reasonable layout, improve the material and heat exchange rate of thermal energy, so that the material drying effect is good; less investment basis, only one-half of the same production single cylinder drying machine reduce the time investment; reliable operation, low energy consumption, high thermal efficiency; at the same time, easy to implement automatic control, reduce operating personnel, labor-saving resources.
Three drum dryer is mainly used for drying certain humidity and particle size range of materials. Such as sand, sand, slag, cinder, small
Size clay, and other small particles of material is not afraid of high temperature and dust soiled. After drying the moisture content of materials can reach 1-0.5% or less.
