Fly Ash Dryer

Fly Ash Dryer

Fly ash drying equipment  its structure is compact,footprint is small,it is a half of single dryer with same yield,work is reliable,energy consumption is low,thermal efficiency is high,the effect of materials dry is good,and it is easy to automation control and less operators.

 In the power plant's coal-fired boiler system,discharging fly ash can be divided into dry discharging and wet discharging. At present,in the cement industry developed areas,dry fly ash is the mixed material for cement production,the market is good, it has shown a trend in short supply and jump to be a source;wet fly ash's every physicochemical property is same with the dry fly ash,only due to the moisture is big(the maximum can reach 45%),it can't meet the cement production's requirements,and don't receive market favour,so it is only stacked in the wet gray library, greater accumulate and more,pollute the environment seriously. With the continuous optimization of the national industrial policy,environmental regulations are severe. The duly handle of wet fly ash has been put on the agenda.Only dry the wet fly ash in reasonable energy consumption and simple process to make low water,so that it can change waste into treasure,and realize the double harvest of social benefits and economic benefit.Fly ash dryer is widely used to solve the fly ash pollution problems and disposal problem,at the same time change fly ash into treasure and increase economic benefits.

>>Fly ash dryer's working principle and characteristics:

  Fly ash dryer is suitable for drying fly ash, phosphogypsum and titanium gypsum and other industrial dust,waste residue,etc. Its working principle is:powdered or granular fly ash deliver into the feeder by belted feeder,then the feeder deliver fly ash into dry rotary drum,the fly ash evenly dispersed and contact with air fully under the uniform copy plate flip in the dry rotary drum,reaching the purposes of heat transmission and mass transfer. After drying, fly ash is discharged as finished products through the unloader in the rotary drum terminal,then the belt discharging machine output the products,completing the drying process.

>> Features

Fly ash drying equipment is designed for the fly ash,whose moisture is higher than other materials,proportion is smaller than other materials,mobility changes great during drying process. So its structure is compact,footprint is small,it is a half of single dryer with same yield,work is reliable,energy consumption is low,thermal efficiency is high,the effect of materials dry is good,and it is easy to automation control and less operators.

1, the outlet temperature is low, the dust removal device can be used for a long time.

2, adopt new combined lifting device, according to users' requirements,it is easy to regulate the final moisture indicators.

3, high degree of automation, easy to operate, smooth operation.

4, the equipment investment required is 1/6 of the imported products, a small investment, faster gains.

5, adopt wheel rotation, small transmission power.

6, footprint is less about 50% than single dryer,the construction investment can reduce about 50%,power consumption is less than 60%.

7, The fuel can adapt the coal,oil,gasoline.
