ABSTRACT:
A process for manufacturing an improved flight assembly for a vertical centrifugal separator. e.g., of the type used to dry coal, is disclosed. The flights are first welded to the cone on which they are to be carried, then the outside edges of the flights are machined, for example on a vertical mill, after which a hard facing is applied to at least a portion of each flight. Preferably a stabilizing ring is welded to the bottoms of the flights before machining. A machining tolerance of plus or minus 1/64 inch (with respect to the gap between each flight and the surrounding conical screen with which the flight assembly is to be used) is preferred. The hard facing may be a weld having a hardness of at least about 40 Rockwell (C scale).
