Introduction of Fly Ash Dryer
Fly ash (coal ash, pond ash) is a by-product powder generated from coal-fired boiler combustion. Once dried, it finds wide applications: cement & concrete production, urban landfill, sewage purification, acidic soil improvement via fertilizer formulation, industrial wastewater treatment, and laboratory test substitutes.
As a trusted manufacturer, Dongding’s fly ash dryer comes with innovative structural design. It can continuously dry large volumes of wet fly ash, reducing its moisture content from 35% down to around 8% efficiently.
Advantages of Fly Ash Dryer
01
Long-Lasting Dust System
Low outlet temperature extends the service life of the dust-cleaning system.
02
Adjustable Output Moisture
New-type lifting boards let the output moisture be adjusted to the customer's demand.
03
Automated & Stable
High degree of automation with simple operation and stable running.
04
Low Transmission Power
Gear transmission needs only a small transmission power.
05
Anti-sticking Design
Optimized internal structure enhances material sweeping and heat transfer, prevents cylinder wall sticking, suitable for high-moisture & sticky materials.
06
Low Investment & Fast ROI
Low equipment investment and operating cost with quick return on investment.
Working Principle of Fly Ash Dryer
Firstly, the raw material transported to the screw conveyor by the belt conveyor, then go into the rotary drum, after drying, most of the dry material will be discharged through the belt conveyor, the left material will go into the cyclone dust collector, where the dust will be collected, with the function of induced draft fan, the left material will discharged through the conveyor.
