1. A rotary screen separator for processing feed material comprising liquids and solids, the rotary screen separator comprising:
a separator member defining a longitudinal axis, an input port, an output port, a first perforation region, and a second perforation region, where
the first perforation region is arranged between the input port and the second perforation region,the second perforation region is arranged between the first perforation region and the output port, andperforations in the first perforation region are smaller than perforations in the second perforation region; at least one collector structure; and first and second vane structures supported relative to the separator member; wherein rotation of the separator member causes the first vane structure to displace the feed material through the first perforation region at a first material displacement rate; rotation of the separator member causes the second vane structure to displace the feed material through the second perforation region at a second material displacement rate; and the first vane structure defines a first pitch and the second vane structure defines a second pitch, where the first pitch is greater than the second pitch such that the first material displacement rate is greater than the second material displacement rate. |
