Fly ash dryer

Fly ash drying plant applies to fly ash, phosphogypsum and titanium gypsum, clay, sand, slag, etc. Industry dust, waste residue drying. Fly ash drying plant is designed by the features of early moisture is higher than other materials; the proportion is less than other materials, big flow ability during dry process.

It is mainly used for building materials and chemtry production in the fly ash, clay, slag, coal, ore drying etc. It is composed of three concentric circles of different diameters embedded in each other combination as the main part. The main art rotates the four tugs5 on both sides through the two tyres4.

The advantages of the fly ash dryer

1. The investment required is 1/6 of the imported products.

2. It will ensure you the final material a moisture below 0.5% which is the first product of ash and slag product line.

3. Cylinder self-insulation thermal efficiency as high as 80% (traditional monocular dryer thermal efficiency was only 35%) to improve thermal efficiency of 45%.

4. Fuel, kerosene vapor applicable. 20mm below the block to dry powder material feed pellets.

5. Dryer than the monocular area of about 50% reduction, 50% reduction in civil engineering, power consumption decreased to 60%.

6. Use and manufacture than ordinary steel, alloy steel wear plate 4 times.

7. Can be customized easily control the required final moisture indicator.

8. Outlet temperature is low, dust removal device a long time.

9. The size of gears without using the tugs turn.

Design system of fly ash dryer

1. Control the early moisture content: The moisture of wet fly ash drying plant which just discharged from the power plant is in commonly around 45%. If dry the fly ash at once, the production cost is higer, it will form bigger pressure to the equipment. If pile up at a draughty area for about 15 days, the moisture of fy ash reduced to about 20%, then handle the materials is a better way.

2. The selection of dust collector. Because of fine fly ash particle, light density, in negative pressure state after drying, it is easy to take away by airflow, lead to the fluid media change, and the dusty gas moisture is bigger.

3. Dry materials conveying equipment should pay attention to seal.

4. The selection of hot air stove. Hot air stove should be choosed high efficiency, fully burn poor quality coal, convenient operation of the furnace type.
