Abstract

The present invention relates to a screening arrangement comprising two side walls, each having an inward facing side and an outward facing side, and a screen holder arrangement (2) extending betweensaid inward facing sides of said two side walls for use in connecting a first and a second screening element (92), said screen holder arrangement comprising: a first screen connector (21) and a secondscreen connector (22), wherein said first screen connector comprises a pivotable element (212) arranged to pivot about an axis that is parallel with a longitudinal extension of said first screen connector, wherein said pivotable element comprises a connection portion (213) arranged to hold one end (911) of said first screening element, and said pivotable element is arranged to pivot between a first position and a second position, respectively, wherein said pivotable element is arranged such that when it is in said second position and a screen is connected to said pivotable element, particleslarger than a predetermined size are prevented from passing between said first and second screen connectors. The present invention relates to a screening arrangement comprising two side walls, each having an inward facing side and an outward facing side, and a screen holder arrangement extending between said inward facing sides of said two side walls for use in connecting a first and a second screening element, said screen holder arrangement comprising: a first screen connector and a second screen connector, wherein said first screen connector comprises a pivotable element arranged to pivot about an axis that is parallel with a longitudinal extension of said first screen connector, wherein said pivotable element comprises a connection portion arranged to hold one end of said first screening element, and said pivotable element is arranged to pivot between a first position and a second position, respectively, wherein said pivotable element is arranged such that when it is in said secondposition and a screen is connected to said pivotable element, particles larger than a predetermined size are prevented from passing between said first and second screen connectors.

Description

technical field [0001] The present invention relates to a screen holding device, a screening arrangement and a screening device for screening of materials in a mobile crushing and screening plant. Background technique [0002] Commonly used screening devices generally comprise a plurality of screening elements arranged in sequence for sorting material streams into different size classes. Measured along the conveying direction of the screening device, the screening elements can be tensioned longitudinally or transversely. For screening elements tensioned in the longitudinal direction, each screening element generally comprises a tensioning device arranged at one end, and a fixed connection point arranged at the other end of the screening element. In conventional screening devices, the tensioning elements are located on the outside of the screening device and the fixed connection points of the screening elements are arranged in the middle region of the screening device. Ther...
