  • Patent number: 11986857
    Abstract: A screen medium of a mobile multi-deck screen is tensioned with a tensioner. A tensioning link engages and tensions a screen medium on a side thereof by at least two linear tension rods, when the screen medium side tensioner is installed to the mobile multi-deck screening device. An adjusting member causes for each of the at least two linear tension rods, a linear movement tensioning by the tensioning link the side of the screen medium above the two linear tension rods. A retractor disengages the tensioning link responsively to untightening the at least two tensioning rods. A screen deck, a screen and a mobile multi-deck screening device are also disclosed as well as a method for replacing a screen medium using the tensioner.

  • Patent number: 11858004
    Abstract: A mobile multi-deck screening apparatus receives material for screening with a feeder of the apparatus. A first screen deck receives and screens material from the feed. A second screen deck receives an undersize fraction of the first screen deck. First and second discharge conveyors output oversize fractions of the first and second screen decks. The first and second discharge conveyors pivot to operate in directions selected between a first direction and a second direction. The first direction is forward. The second direction differs from the first direction. One or both of the first and second discharge conveyors is/are pivotable from one side to an opposite side of the apparatus. Oversize fraction material of the first screen deck and oversize fraction material of the second screen deck are selectively discharged in a common pile.
