Working Principle:

The fluidized bed is divided into the upper and lower bed body, air distributor, the inlet and outlet ports, etc., and the wet material entering the fluidized bed is in contact with the hot air above the air distribution plate, and the material particles are suspended in the air flow to form a fluidized state. The material and the hot air are heat-exchanged and dried, and the finished product is discharged from the discharge port of the fluidized bed, and the dust-containing gas is purified by the dust collecting device and then discharged into the atmosphere by the induced draft fan.

Characteristics:

• Simple structure, convenient overhaul.
• Simple steady operation.
• The air and solid contact evenly with high thermal efficiency.
• Low expenses of equipment maintenance.
• Capable of lower temperature drying for the heat sensitive material.
• Integration of drying and cooling bed, small floor space, low investment.

Applicable Materials: 

Widely applied in chemical, mining, pharmaceutical, food, feed, industrial and municipal sludge treatment industries, Example: choline chloride, sodium bicarbonate, alum, potassium chloride, magnesium sulfate, feed yeast, adipic acid, ammonium nitrate, calcium chloride, calcium hypochlorite, potassium carbonate, potassium sulfate, sodium carbonate, sodium hydrogen carbonate, sodium meta silicate, potassium nitrate, PVC, CPE, PC, etc.
