Types of Centrifugal Fans Used in Dust Collection Systems
Industrial centrifugal fans that provide either forced draft air or induced draft air are commonly used in dust collecting or de-dusting applications. Since these fans produce high pressure airflow they are used in industries to separate solid granular particles from the process steams. Especially, fans with radial tipped and backward inclined are most effective in this process. Whether it is a powered dust or irregularly shaped heavy particles, there are many options available in fan systems to consider for dust collection. Depending on the particle size and volume of the air to filter, centrifugal fans with different blade types can be chosen for an industrial process.
Different Types of Industrial Dust Collectors
Industries use several categories of dust collectors with different filtration and collection processes. For instance, Cyclone dust collectors are typically used for separating heavy dust particles from the air stream. Similarly, Baghouse dust collectors use fabric collectors for accumulating large amount of fine dust particles. Likewise, many types of dust collection systems are used in industrial processes for air filtration requirements. Industrial centrifugal fans play a critical role in providing process air to these systems.
Industries with Dust Collection Applications
Dust collection is one of the critical processes in several industrial segments including cement, food & glass industry, coal & iron, pharmaceutical and others. Depending on the application, centrifugal fan types with varied arrangements (direct drive / belt drive) and blade configurations can be used for any dust collection system. These fans can be installed on the clean side (forced draft) or dirty side (induced draft) of the air based on the process requirement. For instance, in wood industry centrifugal fans with radial blade types are often used to move the dust particles directly through the fan. Similarly backward inclined, airfoil or flat blade centrifugal fans are the right choice for mounting on the top of cyclone in the kiln or within the filtering system to remove the airborne particles.
