Fly Ash Dryer Introduction

Fly ash dryer produced by Fote Machinery is widely used for drying fly ash, phosphor gypsum, industrial dust and waste slag. It is also known as of Powdered Coal Ash Dryer. This dryer is a type of rotary drying equipment and also plays a key part. It has numerous features such as reliable operation, excellent drying effect, high thermal efficiency and large capacity. Besides, fly ash dryer has resolved the pollution and tough disposal problems of fly ash, which not only narrows the pollution, but also turns waste into resources and improves the economic benefit.

Applications of the Powdered Coal Ash Dryer

Adopting new type international technology, Fote fly ash drying equipment is widely used in the advanced utilize of cement clinker, cement mixing materials, large hydro project, pump concrete, large-volume concrete products, high-grade filler, baked brick, etc. Besides, fly ash dryer made by Fote Machinery is commonly used in ore processing, building materials, metallurgy, railway, highway, and other fields for drying materials with certain humidity like ore powder, zin powder, kaolin, limestone, fly ash, phosphor gypsum, industrial dust and waste slag, etc.

Benifits of Fly Ash Dryer

How Fly Ash Dryer Works?

Convection and heat conduction are mainly used in the drying process. When the hot wind in the oven gets the set temperature, the dryer works with the order from the PC system. Wet fly ash is then sent into the inner layer of the fly ash drying equipment by the feeder evenly and goes with the scorching wind. The wet material is sent spirally by the fixed shoveling plate. Next, the material moves to another end of the oven and into the middle layer. This time, wet ash moves forward against the wind stepping back in two steps. Here in the intermediate layer, heat from the inner layer and the middle layer is fully utilized, thus the drying efficiency is improved to the best situation. Lastly, dried fly ash gets to the other end of the intermediate layer and into the outer layer moving in rectangular and multi-loop mode. Fly ash that is dried to satisfactory is blown out of the dryer with the effect of the hot wind. The other will move more slowly on its weight and be dried one more time in the outer layer to required humidity.

Environmental Protection Values of Coal Ash Dryer

In coal-fired boiler of the power plant system, the emission of coal ash can be divided into 2 types, dry emission, and wet emission. As a kind of favorite resources, dry coal ash is of great economic value; wet emission will cause certain pollution to the environment. Processing of moist coal ash has grown up to be an urgent problem at present.

Fly Ash Dryer recycles the burnt coal powder and dries it into fly ash that can be used in concrete and other fields. It is an energy-saving process. This dryer and the collector equipped collecting the ash avoiding it getting into the air or the rivers, which is environmental protection. Compared to the traditional dryer, this new type Fly Ash Dryer gives a maximum utilization of the heat. Efficiency is upgraded and fuel is saved.

Value of Fly Ash Dryer

The Usage of Fly Ash:

Fly ash is mixed material produced by coal powder when it is burned at high temperature (some like volcanic ash). Coal powder is milled into particle less than 100 micrometers and is burnt into high temperature smoke mixed with lots of incombustible matter. With the dust collecting system, we go to get the fly ash. Environmental pollution and energy waste are aroused if fly ash is not utilized rationally. For the recycling, the Fly Ash Dryer is born.

Dried fly ash can be used to make cement clinker, baked brick, aerated concrete and hollow brick for the construction of roads and dams. In addition, the floating beads, microbeads, powdered iron, carbon and aluminum can be selected from fly ash to make other materials.
