Abstract

A screen exchange device (1) for hammer mill (2) comprises a rotatable support structure consisting of shaft (13), plates (20) and associated parts, for supporting several screens which slide longitudinally within the support structure. The drawing shows in continuous lines the end of the screen protruding from the mill. The screen is slid out of the mill by a displacement cylinder, displacing strips (9, 67) in slots (33) formed by the beams (22, 32) and mounted in the beams (21), until it is in the position shown in broken lines in which movement is limited by a stop (43) cooperating with the end of the piston rod. The support structure is then rotated by a motor (18).
