Abstract

The present invention relates to a screening apparatus comprising an outer housing with connections for material to be treated and material treated, end pieces, a stationary screen drum (5) disposed inside the housing (1) and secured with bolts (20) at its upper end flange (14) to an intermediate ring (16) and supported via the intermediate ring (16) by the housing (1); and a rotating rotor (6) disposed inside the screen drum. The screening apparatus is characterized in that the bolt (20) heads are locked to be non-rotatable with a means (18, 22) which leans against at least one side of the bolt (20) head.
