Apparatus and method for distributing a particulate charge over an article

摘要

An apparatus and method for distributing a charge falling onto an article. The apparatus includes a baffle to present a continuous deflection surface to the falling charge, the deflection surface deflecting at least a portion of the charge radially outwardly, and a guide arranged downstream of the baffle to deflect at least a portion of the charge radially inwardly to cause the charge to fall onto the article with a required distribution. The baffle and the guide may be adjustably mounted such that the relative positions of the guide and the baffle can be adjusted to achieve a desired distribution of the charge.
