<p>The machine is comprised of a modular rotary drum (10) comprised of different individual sections (10a, 10b, 10c, 10d, 10e) having each a truncated shape converging in the forward moving direction of the objects to be sorted. The walls of the different sections are perforated with calibrated sorting holes (26) whose gauge increases from the inlet towards the outlet. The internal walls of the different sections are provided with metal sheets describing a spiral which provides for the guiding of the charge to be sorted, during its forward moving. Each sorting hole (26) has the shape of an elongate slot which widens in the forward moving direction. Application to the sorting of the charge of horizontal crushers.</p> |
