ABSTRACT:
A rotary atomizer has an internal chamber for mixing of coating material. The chamber may contain ridges and grooves, as well as a series of shearing posts to mix the coating material flowing therethrough. As a result of centrifugal forces due to the spinning of the atomizer, the chamber is maintained at a negative pressure, which prevents air from being pumped into the coating material. The coating material enters the chamber through an entry passage and is forced toward the outer edge of the chamber over radiating grooves and ridges, which mix and shear the coating material while guiding the coating material toward rows of shearing posts. The shearing posts further shear and condition the coating material. The series of mixing and shearing of the coating material results in a well-mixed coating material at improved viscosity for proper atomization. The coating material then passes through a series of outlet holes, which again mix and shear the coating material subsequently guided to an outer rim of the atomizer for atomization of the intended object. As a result of the shearing and mixing, the object obtains a much improved appearance in terms of smoothness, gloss, and texture.
