Powder coating line

Description

The input to the cyclones is connected to the booth whileCyclones are popular for powder recovery, especially if color change are involved, as cleaning is comparatively easy compared with cartridge filters. Also in automated systems at high throughput rates, cyclones enable oversprayed material to be collected continuously at the required speed.
  The output is connected to a suitable exhaust fan. The overspray powder arrived at the cyclone inlet at a velocity of about *0 m/s. On entering the cyclone chamber tangentially the air/powder mixture is given a rotary motion which creates a centrifugal force on the particles. The larger and heavier particles tend to be ejected to the outside walls of the chamber and fall to the bottom is deflected by a conical tail air/powder mix into a rising spiral which is then carried through the central stack to a filter collector.
The recovered powder is removed from the cyclone by means of a rotary valve and is then passed through a sieve to remove any agglomerates and foreign matter. The recovered powder is then blended with the virgin material in predetermined proportions.
