Principles of Air Separator:
Air Separator Separates particles based on size, shape, and density using an airflow.
Lighter and finer particles are carried away by the air stream, while heavier particles settle.
Construction:
Separation Chamber: A vertical or horizontal chamber where separation occurs.
Fans/Blowers: Generate the airflow required for separation.
Inlet: For feeding the material to be separated.
Outlets: Separate outlets for light and heavy particles.
Control System: To adjust the airflow and separation efficiency.
Working:
The material is introduced into the separation chamber.
Airflow generated by fans blows through the chamber.
Lighter particles are carried upward or downstream with the air, while heavier particles fall due to gravity.
Separated particles are collected at different outlets.
Uses:
Classification of powders in the chemical, pharmaceutical, and food industries.
Used in milling operations to separate fine particles from coarse ones.
Merits:
Can handle a variety of particle sizes and shapes.
Adjustable to achieve desired separation efficiency.
Suitable for continuous operation.
Demerits:
High energy consumption due to the use of fans.
Not effective for particles with similar densities.
Potential for air pollution if not properly controlled.
