A system for comminuting solid waste material including a shredding device disposed within the casing and comprising parallel first and second shredding stacks that include first and second parallel shafts rotatably mounted between an upper shredding device housing and a lower shredding device housing and a rotating screening drum disposed within the casing and mounted between an upper screening drum housing and a lower screening drum housing, the rotating screening drum configured to permit fluid to pass therethrough while capturing solids on an outer surface for delivery to shredding device, an upstream portion of the rotating screening drum disposed upstream of an upstream portion of the shredding device. The upper shredding device housing and the lower screening device housing are separate members from the upper screening drum housing and the lower screening drum housing to permit interchangeability of different sizes of these components to meet system needs.

The present invention relates to a device for treatment of a material mixture consisting of substitute fuel and impurities, having a vertically aligned central feeder (1), a separating unit (2) arranged underneath the central feeder (1), a rotor mill (3), wherein the rotor mill (3) is arranged above the separating unit (2) and surrounds the central feeder (1), a flow device (4) for generating an upwardly directed gas flow, wherein the rotor mill (3) has a multistage design, and a respective separating device (6) is arranged between the stages (5.1, 5.2) of the rotor mill (3), wherein material mixture not held back by the separating device (6) is further comminuted in the following stage (5.2).

A method of treating and grading contaminated particulate material includes i. physically breaking up the particulate material to separate the particles thereof; ii. rinsing and grading the particulate material to separate the particulate material into an oversize fraction and an undersize fraction; iii. washing and grading the oversize fraction to produce one or more treated aggregate products; iv. passing the undersize fraction through a high shear washing process to separate contaminants therefrom; v. fluidising and cleaning the undersize fraction in a classification tank to produce one or more treated sand products at an underflow thereof by passing clean water upwardly into the classification tank. Optionally, waste water resulting from stages (ii), (iii) and (iv) is treated to form process water, a portion of which is used in stage (ii), a portion of the process water undergoing one or more further treatment processes to produce clean water used in stage (v).
