Processing of pre-treated mixed waste

摘要

Disclosed herein is a processing plant (10) and a method for processing residual material from upstream mixed waste treatment processes. The plant (10) a comminutor, preferably in the form of a flail mill (12), for comminuting residual material input into the plant to reduce its average particle size. Downstream of the flail mill (12) is a first screen (14) having openings with a maximum dimension of less than around 30mm. A second vibratory mesh screen (16) may be provided downstream of the first screen (14) to screen material that is caught by the first screen (14). The second screen (16) may have openings with a greater maximum dimension than that of the first screen (14). Conveyors, such as continuous belt conveyors (18) and augers (20), may be provided to move material through the plant (10).
