Q235 Cement Rotary Kiln Direct Drive Type Centrifugal Blower Fan
Introduction
Centrifugal blowers are widely used in sewage treatment, smelting
blast furnaces, coal washing plants, mine flotation, chemical gas
production, vacuum and other fields, and can also be used to
transport other special gases.
The centrifugal blower has compact structure, beautiful appearance,
good stability and easy installation and maintenance.
Q235 Cement Rotary Kiln Direct Drive Type Centrifugal Blower Fan is
suitable for the ventilation and induced draft fan systems of
2~670T/h steam boilers in thermal power plants.
It can also be used for mine ventilation and general ventilation
without other special requirements; Mainly used to meet the needs
of large air flow applications, low noise and high efficiency.
They can transport clean gas, dusty gas, flammable gas, corrosive
gas, powder or granular materials at normal temperature or high
temperature.
Application
Typical applications include: building ventilation, mine
ventilation, smoke evacuation, drying, clinker cooling, transport
of gas, transport of lightweight materials, blasting and drafting
of industrial boiler systems, and supply of air to kiln
systems/incinerator systems and induced air, air purification
equipment, industrial dust collector systems, etc.
In addition to the industrial system, it is also frequently used in
agriculture and civil applications and the most versatile range of
centrifugal fans.

Advantages and Features
1. It can work stably at a high medium temperature, and can output
a large gas flow with low noise when the pressure requirement is
met.
2. The fan blade placement angle is optimized, more wear-resistant
and longer service life.
3. The air damper can be used to flexibly adjust the pressure and
flow of the fan during operation. It is also possible to select a
variable frequency motor, with adjust the pressure and flow of the
fan by changing the speed.
4. For the material of impeller and main shaft, we will choose
high-strength carbon steel, low-alloy steel, high-temperature alloy
steel, high temperature resistant high-strength alloy steel under
different working conditions temperature and working speed, so that
the impeller and main shaft still maintains a reliable strength at
high temperature.
5. Fan systems with impeller diameters less than 1400 mm at normal
temperature do not require additional bearing cooling devices,
reducing users’ investment and maintenance.
6. The impeller is annealed to eliminate the internal stress
generated during welding, ensuring that the impeller does not
undergo creep and cracks.
7. The weld of the impeller and the main shaft are ultrasonic flaw
detection to ensure that there are no welding defects and material
defects to ensure strength.
8. The impeller is subjected to a high standard of dynamic balance
correction to ensure stable operation of the fan.
9. There are a variety of accessories to choose from.
