  • Publication number: 20230405636
    Abstract: A mobile aggregate processing plant for screening material including a chassis and a vibrating screen support frame, and a vibrating screen mounted on the support frame, wherein the vibrating screen has an infeed end and a discharge end, and able to provide at least one material discharge stream therethrough. A feed hopper has a discharge end able to feed a stream of feed material into or onto the vibrating screen. A shredding apparatus is moveable between at least a first in use position above the infeed end of the vibrating screen and/or next to the hopper discharge end, and a second transport position not above the infeed end of the vibrating screen and/or not next to the hopper discharge end.

  • Patent number: 11033933
    Abstract: A mobile aggregate processing plant for screening aggregate material comprising a mobile chassis, a vibrating screening unit mounted on the mobile chassis and able to provide at least one aggregate discharge stream therethrough, and an underscreen conveyor located wholly or substantially beneath the vibrating screening unit to wholly or substantially receive said at least one aggregate discharge stream, wherein the underscreen conveyor is driveable in an uphill direction so as to be able to discharge the aggregate discharge stream at a height higher than receiving the aggregate discharge stream, relative to the mobile chassis.
