The fly ash dryer is a specialized equipment for drying fly ash, mainly used for processing industrial dust and waste such as fly ash, phosphogypsum, and titanium gypsum. The working principle is as follows: powdered or granular fly ash is transported to the feeding machine through a belt feeder, and then the feeding machine transports the fly ash to the drying drum. In the drying drum, fly ash is uniformly dispersed under the flipping of a uniformly distributed plate reader, and fully contacts with hot air to achieve the drying purpose of heat and mass transfer. The dried fly ash is discharged as a finished product at the end of the drum through a discharge device, and then output through a belt discharge machine to complete the drying process.

Characteristics of fly ash dryer

Efficient drying: The fly ash drum dryer uses multiple layers of lifting plates and guide plates to form a uniform material curtain inside the drum, resulting in more uniform heating and a larger evaporation area, thereby improving drying efficiency.

Low energy consumption: Adopting countercurrent drying method, utilizing high-temperature flue gas to achieve high evaporation intensity, reducing fuel consumption, and improving thermal efficiency.

Strong adaptability: The equipment has strong adaptability to different materials, can handle materials with various moisture contents, and can control product particle size and moisture.

Structural optimization: The new feeding and discharging device reduces blockage and material return, and lowers the load on the dust removal system.

Smooth operation: The equipment adopts a "self-aligning supporting wheel installation" to reduce wear and power loss, ensuring smooth operation of the equipment.

Application fields of fly ash

Fly ash dryers are widely used in industrial fields such as coal washing plants, power plants, and smelters, mainly for drying and dehydrating slag and fly ash. Through efficient drying treatment, the moisture content can be controlled below 10%, effectively solving the problem of slag pollution.
