Description of Fly Ash Dryer:
Fly ash dryer is mainly used for drying certain humidity range granular materials. It is applied to drying fly ash, phosphorous gesso and titanium gypsum and other industry dust. The fly ash dried by fly ash dryer can used as admixture with cement, mortar and concrete，and become part of the cement and concrete. Fly ash can be as raw materials instead of clay, production cement clinker, sintered brick, autoclaved aerated concrete, cellular concrete, hollow bricks, sintering or non sintering ceramsite, paving the way, construction of the dam and so on. According to different industries with different requirements of final material moisture, drying of material moisture content can reach less than 1-0.5%.
Working Principle of Fly Ash Dryer Machine:
In hot blast furnace hot blast temperature is 350 DEG C, in the PC system directed, the equipment to work. Wet material conveying equipment to water less than 20% wet fly ash into the scatter feeding machine, feeding machine with scattered scattered and conveying a dual function, so that the material uniformly into the conveyor belt, then enters the storage bin, and then after the screw feeder, even put fly ash into the drying drum. The device can save energy 1/3, greatly reduces the cost of production, the technology in the domestic leading level, its working principle is as follows: Material to be dried enters the dryer, and as the dryer rotates, the material is lifted up by a series of internal lifting flight lining the inner wall of the dryer. When the material gets high enough to roll back off the fins, it falls back down to the bottom of the dryer, passing through the hot gas stream as it falls. Rotary dryer can be widely used to dry various materials, and it is simple to be operated.
Features of Flyash Dryer:
1. Equipment investment is imported products 1/6, small investment, gains fast.
2. The final material moisture that is below 0.5%, fly ash and slag powder production line first products.
3. Excellent heat preservation ,the thermal efficiency can reach above 80%,increased by 45%(The heat efficiency of traditional dryers is merely confined to 35% ).
4. Adopted alloy steel plate with abrasive resistance 4 times than common steel plate .
5. The fuel can be applied to coal, oil, gas and other.
6. The rotation is through the wheel, not required wheel gear in large and small size.
7. According to the requirements of users can easily control needed for final moisture index.
8. The eventually moisture indexes can be adjusted on the ground of consumers'needs .
