Application of rotary dryer:
Rotary dryer can dry many kinds of materials which contain moisture, such as coal, coal slurry, slag, industrial waste, and clay stone. Rotary dryer are widely used in building materials,metallurgy, and chemical industry. Rotary dryer is handling by bringing it into direct contact with a heated gas. The dryer is made up of a large, rotating cylindrical tube,the dryer slopes slightly so that the discharge end is lower than the material feed end in order to convey the material through the dryer under.
Working Principle of rotary dryer:
It mainly consists of revolution body, raise material board, transmission device, supportive device and sealing ring, etc.
The heat sources of the drier is from the combustion train, and is adopts down-flow heating methods. When the materials enter into the body from the feeding device, it will be pushed back by the spire raising board. As the drier is in an inclined position, the materials will be down to the lower end under the influence of gravity and rotation, but the raising board will be threw to the upper end for scattering. This procession makes the material well-distributed in the body, and then ensure the heat exchange with the heat wind. After repeated cycle with this procession, the moisture content will be dried.
Features and Benefits:
1, large intensity of drying, high dispersion due to the material in the air, all the surface area of particles extremely dry effective area.
2, short drying time
3, air dryer structure is simple, cover an area of an area small, easy to build and repair.
4, large capacity, high thermal efficiency. When drying the combined water, the thermal efficiency can reach 60%.
5, dryer to achieve the "zero thrust", greatly reducing the wheel wear, shell smooth and reliable operation;
6, drying machine adopts "self- aligning roller device", make the wheel and roll ring with a linear contact forever, thus greatly reduces the wear and power loss;
