【Feature of Fly ash dryer】
Fly ash dryer applies to fly ash, phosphorous gesso and titanium slag, gypsum industry dust,
Fly ash drying equipment has the advantage of reliable, low energy consumption, high thermal efficiency, material drying effect is good, easy to realize automation control, few operators. Fuel can be coal, oil and gasoline.
fly ash drying process can be adopted for the downstream counter-flow drying process)
【Working principle of Fly ash dryer】
Powder or granular fly-ash was transported to the hopper by the belt conveyor or bucket elevator, and then enter into the feed end through the feeding tube by the hopper feeder. Slope of the feeding pipe must be greater than the natural angle of material so that the materials can flow into the sand dryer. Dryer cylinder forms a slightly tilted with the horizontal. Material was added from the higher to form reflux with the heat carrier entered from low-end. Sometimes, heat carrier flows into the cylinder together with the material. With the rotating of drum, material run to the lower end by gravity. In the moving process, wet materials obtain the heat input of heat carrier directly and indirectly to be dried, then, the finished materials are sent out by belt conveyor or screw conveyor.
