Polex’s diverse range of cyclones

Cyclones are primarily used for the collection of dust particles from an
airstream in a processing or manufacturing environment. Offered by Polex Environmental Engineering in a broad range of models in various materials and
finishes, these cyclones find application in powder processing plants, timber
workshops and manufacturing plants.

Featuring a fully welded galvanised sheetmetal construction, Polex cyclones
are available in different specifications in terms of body and air discharge
diameter, height, thickness and airflow capacity to meet the diverse
requirements of end applications.

Cyclones are generally used for pre-separation of large dust particles
from an airstream while finer and lighter particles are generally collected by
fabric dust collectors located further downstream of the process. Rotary valves
connected to the cyclone’s product discharge feed the collected dust into
collection bins below, or into other equipment such as screw conveyors,
transfer fans and silos. A cyclone can be designed for specific airflow
requirements.

How it works

Polluted air first enters the cyclone through a rectangular inlet near
the top, producing a centrifugal force that pushes the dusty air downwards. While
the heavier dust particles are forced onto the walls of the cyclone due to the
centrifugal force only to fall into the bin below, the lighter and finer
particles travel up through a cylindrical tube located in the centre of the
cyclone and exit for further filtration by other equipment such as fabric dust
collectors downstream.

Polex cyclones are available with various options such as fans, dust
collectors, ducting, silencers, electric controls and rotary valves.
