                                    Working of Hyper Cyclones:
The Hyper Cyclone (one or more) represent the powder overspray recovery system of the
powder coating booth (the spray section). The work-pieces, duly jigged are hung on the jigholder
in the coating booth (manually or pass on a conveyor line) and sprayed with powder.
A specially designed low-pressure, high capacity air extraction fan sucks air and the powder
overspray through the coating booth, through the ducts to the Hyper Cyclone recovery
system. Hyper Cyclones have a critical design factor as they are designed and built to work
specifically for powder coatings and the normal particle size distribution associated with
powder coatings.
The HC entry is such that the powder particles are forced in a cyclonic pattern through the
side near the top in the cylinder of the Cyclone. As these powder particles spin round the
cylinder in their specific pattern, they descend due to gravity. Horizontal and vertical forcemix
on the powder particles ensures that they drop down into the powder bin below the
conical part of the cyclone. Virtually clean air is sucked out through the central outlet in the
top of the cyclone. More than 95% (often as high as 98-99%) of the powder particles get
collected in the powder bin.
Powder particles, referred to as ‘fines’ (very low weight and sized particles) where the
horizontal cyclonic and vertical gravitational force-mix do not match also get sucked out with
the air. These remaining powder particles are trapped in the after-filters, allowing virtually
clean air back to the shop-floor atmosphere.
