ABSTRACT:
A slide plate screen changer has a housing defining a material flow passage and a transverse slide plate passage in which is mounted a movable screen plate. Seal rings on the upstream and downstream sides respectively of the screen plate prevent leakage of material from the flow passage. One of the seals is adjusted by means of a threaded bushing which surrounds the flow passage and which protrudes axially from one end of the housing where it is fully accessible to torque exerting tools.
