The machine consists of a horizontal or slightly inclined rotary drum (10) made up of a number of sections (10a - 10e) with apertures (26) increasing in size in the direction of the flow through the drum. Each drum section has a truncated conical wall which converges in the direction of the flow, with the apertures in the shape of slots of increasing size in the same direction. Each drum section is in the form of a separate module which can be detached from the adjacent sections, to which it is connected by bolted flanges (14, 16). The end flanges of the first and last drum sections are supported by roller bearings (18, 20). The inside of each drum section has guide vanes, and the slots are inclined relative to the direction of travel. |
