Abstract

See full text

A screening machine includes a rotary trommel screen having an overall length. The rotary trommel screen has an inlet and an outlet end. The screening machine includes a first collection area proximate to the inlet end and under the rotary trommel screen. The first collection area corresponds to at least 65 percent of the overall length of the trommel screen. The screening machine includes a second collection area proximate to the outlet end and under the rotary trommel screen. The second collection area corresponds to the remainder of the overall length of the trommel screen not corresponding to the first collection area. The first and second collection areas are configured to separate a first and second product respectively. Sections of the trommel screen corresponding to the first and second collection areas are configured such that a size of the first product is different than a size of the second product.
