A device for separating a metalliferous, lumpy mixture, with a conveyor belt and with a rotating drum in which a fixed magnet system with at least one magnet line is arranged. The separating effect of the device is improved and its complexity is reduced where it is provided that the magnets of the at least one magnet line are arranged such that their poles have the sequence NS SN or SN NS in the circumferential direction, as a result of which the ratio of the maximum radial magnetic flux density to the maximum tangential magnetic flux density on the belt surface, facing the material, in the region of the magnet system is greater than one and, owing to this, the electrically conductive particles are separated out into the first partial stream by radial force action (repulsion).

An apparatus for carrying out size reduction of battery materials under immersion conditions having a battery inlet and at least a first comminuting device disposed within a housing and configured to cause a size reduction of the battery materials to form reduced-size battery materials and to liberate electrolyte materials and a black mass material comprising anode and cathode powders from within the battery materials. An immersion liquid can be within the housing and can submerge the first comminuting device so the black mass material and the reduced-size battery material are entrained within the immersion liquid to form a sized-reduced feed stream. A feed outlet may be downstream from the first comminuting device.

A braking system for safely collecting brake dust produced by operation of a braking mechanism. The braking system comprises a collector apparatus coupled with a braking mechanism. The collector apparatus is able to include a shroud that surrounds the braking mechanism and a catch element coupled with the shroud for collecting brake dust exiting the shroud. As a result, when coupled with the braking mechanism, the collector apparatus is able to ensure that most or all brake dust, such as copper or other particles from the braking mechanism that break off from the breaking mechanism during operation of the braking mechanism, are removed from the braking mechanism and collected by the filter/catch of the collector mechanism.

A system and process for sorting and recovery of recyclable materials, and in particular, sorting and recovery of recyclable materials from mixed waste comprising municipal solid waste in a materials recovery facility.
