Abstract
A static classifier cage is formed in upper and lower tiers of circumferentially spaced bar-shaped vanes of wear-resistant material. The lower tier is formed by and between a bottom ring and an intermediate ring. The top tier is formed by and between the intermediate ring and a topmost ring. In each tier, the lowermost ring is provided with slots to receive and act as a seat for the vertically oriented vanes while the upper ring in the tier is provided with radially outwardly opening notches into which the vanes are moved in a radial fashion. After the vanes are installed, a retainer is fastened into position to prevent the vanes from backing out of the notches.
