Materials are sent to hopper of rotary dryer by belt conveyor or bucket elevator. The barrel is installed with slope to horizontal line. Materials enter the barrel from the higher side and hot air enters the barrel from the lower side materials and hot air mix together.
Fresh air is sucked through hot air generator, which can be direct or indirect the nature. The entry to the drying chamber is tangential to give whirling air suction across the dryer. The hot air generator can be liquid, solid or gaseous fuel fired.
Kaolin dryer is widely used for drying concentrate powder, slag, limestone, coal, slag, clay, kaolin in and other materials in building materials, metallurgy, chemical industry, cement industry, etc. it is especially suitable for kaolin, clay and bentonite.
The hot air produced by the direct combustion hot blast stove enters into the kaolin dryer and makes full contact with the material, to dry the material rapidly, and then the dried material will be discharged through the conveyor installed at the discharge end of bentonite dryer.
The Super Rotary Dryer features a disintegrator in the rotating drum to effectively make the material contact with the hot air. Not only the sludge from waste water treatment system but dewatered cake, muddy and solid materials can be dried into granular product continuously and uniformly in a short time.
