3, Product advantages
1. The lifting plate device is adopted, which has many functions
such as guiding, current sharing and lifting;
2. The material can be evenly distributed in the radial section of
the dryer, the material curtain can be thin, uniform and complete,
and can completely contact with the hot air flow, so as to make
full use of the heat energy;
3. It has been widely used in cement and mineral processing
enterprises;
4. With reasonable operation parameters, the coal consumption and
power consumption are lower than those of ordinary dryers.
5, Working principle
When the material enters the dryer cylinder, it is dried by
contacting with the hot air in the cylinder in a forward or reverse
flow or effectively contacting with the heating wall. After drying,
the product is discharged from the lower part of the other end.
In the drying process, the material moves from the high end to the
low end under the action of gravity with the help of the slow
rotation of the cylinder. The inner wall of the cylinder is
equipped with a forward reading plate, which continuously picks up
and sprinkles the materials, greatly enhances the thermal contact
surface of the materials, improves the drying rate and promotes the
materials to move forward.
