ABSTRACT:
An installation for electrostatic deposition of powder on objects travelling continuously, by means of a conveyor, through a treatment cage with a side entrance and exit comprises a filtering system, a system for supplying powder and compressed air and a tank for recovery of powder. The cage comprises at least two modules, namely, a first module for storing, projecting and recovering powder, which contains elements for projection of powder onto the objects to be processed, and a second module for filtering and recycling the air in which the air loaded with powder originating from the first module is filtered and recycled to the first module. The cage includes at least one air lock to prevent escape of powder laden air to the exterior of the cage.
