The cement industry across the world is growing at a decent pace. Considering the 
massive structure of this industry, the manufacturing plants need to deploy different 
types of industrial fans. Cement is extensively used as a binder, mixture, and building 
material. It is a crucial material in the construction and manufacturing industry. From 
buildings to pavements and from dams to surfacing sidewalks, cement continues to 
be a versatile construction material.
Naturally, the high demand for cement requires the manufacturing plants to deploy 
the right kinds of industrial fans. This helps in maintaining the right combustion 
environment.
Why are industrial fans necessary in the cement manufacturing industry?
The manufacturing process of cement calls for specific industrial fans. This helps in 
managing and handling different processes such as grinding, moving, heating, 
cooling, and preheating. Besides, an efficient air filtration mechanism is a crucial part 
of the manufacturing industry to fulfill environmental regulatory norms. This 
explains why cement companies use several types of industrial fans in the process.
The most common industrial fans that cement companies need include forced 
draught fans and induced draught fans. Forced and induced draught fans are used in 
manufacturing furnaces, boilers, ovens, and other industrial components. We are 
going to discuss why these fans are critical in the cement manufacturing industry.
Forced draught fans
The key role of forced draught fans is to create positive pressure around the 
combustion chamber. These fans help in pushing the air in these systems. Right from 
dust collection machines to furnaces or boilers, different parts of the operational 
mechanism need forced draught fans. However, these fans function differently 
based on the place you incorporate them. In furnaces or boilers, forced draught fans 
collect fresh air from the external environment and blow them into the furnace. This 
facilitates the combustion process significantly. The direct drive fan mechanism in 
forced draught fans makes them popular.
Induced draught fans
The operational mechanism of induced draught fans is exactly the opposite of forced 
draught fans. They create a negative pressure in the combustion chamber, drawing 
exhaust gases through the chimney after combustion into the environment. Specially 
built chimneys are necessary to eliminate this air into the atmosphere. However, 
these fans consume more power to operate compared to forced draught fans.
What makes FD and ID fans crucial in the cement manufacturing industry?
Now that you know how FD and ID fans regulate the operational conditions around 
the combustion chamber, it’s easy to understand their importance in the cement 
manufacturing industry. It is necessary for these fans to have proper thickness and 
MOC. This has to be decided on the basis of the amount of dust they need to handle 
and the operational temperature around the combustion chamber. If there are 
excessive dust particles, it would cause the padding to wear away.
One of the prime benefits of using these customized fans is that they produce low 
noise. By reducing the noise level in the manufacturing unit, they enhance the 
working conditions for the staff. This indirectly results in increased production, and 
cement companies can boost their revenue.
