Dryer Introduction:
Dryer is mainly used for drying wet materials in building
construction, metallurgy and chemical industries. It can dry
various materials with strong adaptability. Besides, it is a common
drying device in cement plant with simple and reliable operation.
In our company, this series applies the new type scatter plate
device, and it has many functions, such as guide direction, flow on
an average, scatter the material and so on. And it can make the
material in the thin, average and complete condition. Contact with
the heat airflow completely and use the heat energy fully.
Moreover, it adopts reasonable operational parameter, and compared
with general dryers, it reduces the coal and power consumption
above 10-15%,and increase the output above 10-15% . At present, it
is widely used in cement and miningindustries.
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.
Structures
The rotary dryer is mainly composed by the revolving body, lifting
plate, driving device, supporting device, sealing ring and other
components. So it has the advantages of reasonable structure,
perfect in workmanship, high yield, low energy consumption,
convenient to operate.

1. The motorization level of the barrel is high, and the production
capacity is high;
2. The resistance that the material passes through the barrel is
less, and the power consumption is low.
3. Application capability to different characters of materials is
high.
4. The operation is stable, the operation fee is low, and the
uniformity of product drying is good.
5.The rotary dryer is mainly composed by the revolving body,
lifting plate, driving device, supporting device, sealing ring and
other components. So it has the advantages of reasonable structure,
perfect in workmanship, high yield, low energy consumption,
convenient to operate.
