In the context of industrial processes, there are various technologies that allow the separation of solid particles. If the particles have dimensions greater than 10-50 µm, an apparatus that allows to obtain interesting results is the cyclone. The latter, by means of the centrifugal force, puts the particles in a position to impact against its walls, thus making them fall to then collect in a suitable container.
For smaller particles the cyclonic technology has some limitations, and it is necessaryt to apply mechanical filtration. What is meant by this term?
The meaning is extremely simple: the separation of the solid phase takes place by passing the gaseous stream through a specific filter surface, which retains the particles and separates them from the stream.
