Introduction to Rotary Dryer:
Our rotary dryers are optimized on the basis of regular rotary dryers, making it more efficient to deal with high moisture and sticky materials. the dryer was designed with higher Diameter/Length ratio, unique flight distribution &shape and effective internal breaking mechanism.
Structure and Working Principle of Rotary Dryer:
Rotary dryer can reduce the water content (70% -80%) to safe storage state(water content 13%). The whole process happens in a closed system, thereby reducing pollution of the environment the environment. Equipment mainly composed of screw dewatering machine, hot air stove, feeder, feeding machine, rotary drum, discharging machine, material crushing unit, fan, discharge and power cabinet; after dehydration, the wet material entered the drying machine, both in the drum cloth turning device copy board, the material dispersed in the dryer full contact with the hot air to speed up the drying heat and mass transfer . During the drying process, with a gradient of copy material in the hot plate and under the effect of temperament, to another section of the dryer exhaust discharge valve star products.
Features of Drying Machine:
1. Compared to single cylinder sand dryer, the machine length shortens 60%, in favour of process arrangement. Reduces workshop covered area, reduced the project investment by 40%. Occupation area: about 20m2.
2. Adopted latest technology, cylinder self insulation, thermal efficiency is as high as 80% (single cylinder small dryer is only 35 percent), thermal efficiency than single cylinder drying saves coal 68%, yields 100%.
3. Heat-resisting wear-resisting alloy steel plate, four times than ordinary steel wear-resisting. Long service life and easy maintenance.
4. High thermal efficiency, outside shell temperature below 60 ℃ (single cylinder silica sand dryer outside shell temperature as high as 150 ℃), output of low temperature, discharging temperature below 60 ℃.
5. Output of low temperature, be helpful for dust collector to use a long time, can be directly supporting air tank pulse bag filter.
6. Construction investment reduces 50%, power consumption reduces 60%.
7. Adopts roller rotation, no need reducer.
8. Hot air stove can support fluidezed bed, spray stove, hands burned furnace, also used in fuel and gas type, can bake the below 20 mm pieces of materials, aggregates, powder material.
9. After drying the moisture content of materials is at 1-0.5% and below, which can meet different industrial requirement.
