A screening machine () has a screen tray (), in which at least one screen lining () is disposed between two side walls () wherein a screen tensioner () is assigned to the screen lining (), which screen tensioner () extends, with its longitudinal ends, through a respective feedthrough () of the side wall (). At least one of the feedthroughs (is covered, at least in part, on its outer face facing away from the screen lining () by a removable cover (), wherein the cover () is supported on the outer face of the side wall () by a sealing surface () of a sealing element (), the sealing surface () facing the side wall (), such that dust is prevented from escaping and the operating safety and occupational safety is improved.

Screening machine having a screen tray

A mobile machine for conveying and/or processing mineral aggregate material, includes a machine frame and a conveyor module supported on the machine frame so as to be displaceable relative to the latter. A conveyor line runs along a virtual conveyor path (FB), the conveyor module being designed at least for conveying the aggregate material along the conveyor path on the conveyor line. A component carrier in a working state of the machine runs in an elevation direction (H) at a distance from the conveyor line crosswise with respect to the conveyor path above the conveyor line. The component carrier supports at least one functional module which interacts with the aggregate material conveyed on the conveyor line. The conveyor module is displaceable relative to the machine frame with a displacement component in the elevation direction. The component carrier is movable both relative to the conveyor module and the machine frame.

The invention relates to a rock processing machine () having a feed hopper () and a process unit () downstream thereof, wherein a conveying device, in particular a hopper discharge belt (), is assigned to the feed hopper (), wherein the feed hopper () has a hopper side wall (), and wherein a side-wall heightening () is assigned to the hopper side wall (), which side wall heightening can be swiveled between a folded-down working position and a folded transport position. In such a rock processing machine, the requirements of occupational safety are effectively taken into account in a simple manner if provision is made that an operating unit () having a lever () for swiveling the side-wall heightening () is assigned to the side-wall heightening (), wherein a transmission element () is used to couple the lever () to the side-wall heightening (), and that the side-wall heightening () is secured in the folded-down working position using a movable locking element ().
