In a pneumatic conveyor system, what is the function of a cyclone?

In a pneumatic conveyor system, the primary function of a cyclone is to act as a separator. A cyclone is a mechanical device that utilizes centrifugal force to separate particles from carrying air in a gas-solid separation process. When a mixture of air and particles enters the cyclone, it is spun in a circular motion which generates a centrifugal force that pushes the heavier particles toward the walls of the cyclone. These particles then slide down the wall and are collected, while the cleaner air exits from the top of the cyclone.

This separation function is crucial in many industrial applications as it allows for the efficient recovery of particulate materials, minimizing waste and maintaining air quality. By ensuring that particles are effectively separated from the air stream, the cyclone aids in the overall performance and efficiency of the pneumatic conveyor system. Other components such as motors, compressors, and dischargers serve different roles and do not perform the specific separation task that the cyclone does.
