摘要
The plant is for removing excess paint from articles, typically gratings (30) and has an overhead conveyor (16) with a beam acting as a guide for the conveying chains. This carries the gratings through a tunnel which acts as a refrigeration tunnel, being subjected to the fumes from a bath (20) of liquid nitrogen. When the gratings arrive at a point above the bath, they are lowered into bath for an increased refrigeration to a very low temp. A portion of the beam separates from the remainder so that it can be lowered with a grating suspended from it. It is then raised and the grating conveyed onwards to pass between doors to enter a chamber between shot blasting turbines (2). In their refrigerated condition, the excess paint is more easily removed by the shot blasting turbines (2). In their refrigerated condition, the excess paint is more easily removed by the shot blasting treatment.
