Patent number: 11931746Abstract: An apparatus for processing aggregate material includes a chassis, a trough mounted on the chassis at an inclined angle, and at least one shaft rotatably mounted within the trough and extending from a lower to an upper end of the trough. The at least one shaft has blades mounted thereon, the blades being angled so that they carry material within the trough towards the upper end of the trough when the at least one shaft is in a normal direction of rotation. A discharge opening is formed in a base of the trough adjacent the upper end of the trough, a weir being provided in the trough upstream of the discharge opening over which processed material must pass to reach the discharge opening.Type: GrantFiled: July 24, 2022Date of Patent: March 19, 2024Assignee: CDE Global LimitedInventor: Anthony Convery
