Three-drum dryer is also called three-cylinder dryer and triple-drum dryer. It has improved internal structure of monocular dryer, which prolongs the time of pre-drying of wet materials and wet materials in the machine, thus improving 50% to 80% of production capacity compared with original monocular dryer.
1. The needed investment is only 1/6 of foreign import product.
2. The final moisture of the materials is ensured to be below 0.5%, making it the first choice of dry-mixed mortar and slag powder production line.
3. The self heat preservation heat efficiency of the cylinder can reach as high as over 70%, thus improving the heat efficiency by 35%.
4. The fuel can be coal, gas and oil, and it can be used for drying lump, granulous and powdery materials whose granularity is below 20mm.
5. Compared with monocular dryer machine, its floor space is reduced by about 50%, infrastructure investment reduced by about 50% and electricity consumption reduced by 60%.
6. The needed final water content index can be easily regulated according to customers’ requirement.
7. The temperature of the air out is low and the service life of the dust removing equipment is long.
8. It needs no rack wheel and pinion driving, but uses riding wheel for transmission.
