ABSTRACT:
A classifier for separating particulate matter into relatively coarse and fine particles. The classifier includes a casing, at least one cylindrical screen assembly mounted in the casing and extending substantially in the direction in which the particulate matter flows in the casing for forcing the fine particles to traverse the cylindrical screen assembly, and at least one air purge pipe disposed in the casing for blowing air against the screen assembly to remove particles off the latter screen assembly, the cylindrical screen assembly and the air purge pipe being relatively movable by a drive mechanism. The cylindrical screen assembly has an increased degree of mechanical strength and rigidity, and provides a wide effective area available for screening.
