A system and method for freezing and breaking down tires or other materials is disclosed. The system and method for freezing and breaking down tires includes using a shredder to shred the tires, using a filter to screen the tire shreds, using a water sprayer to rinse the tire shreds, using a freezing tunnel to freeze the tire shreds before they are crushed into tire grains, using a magnet to remove any metallic fibers, filtering out any oversized tire grains for re-freezing and re-crushing, and using a separator to separate out any oversized or undersized pieces before bagging the final tire grains for re-use and recycling.

A method and system of recycling aluminum alloy wheels, the method and system comprising (a) providing a feed of aluminum alloy wheels of a particular alloy; (b) fragmenting the aluminum alloy wheels into a plurality of fragments (c) shot blasting the plurality of fragments to clean non-aluminum contaminants off the plurality of fragments; (d) separating the plurality of fragments from the plurality of shot by moving a mixture of the plurality of fragments and the plurality of shot adjacent a dividing surface; and (e) providing the remaining plurality of fragments for use in manufacturing at least one component made from aluminum alloy.

A method of processing magnetite iron ore, including the step of using a high pressure grinding roller (HPGR) to crush the magnetite. An apparatus for processing magnetite iron ore, including a first high pressure grinding roller for crushing the magnetite, a dry screen for selectively feeding back material to the first high pressure grinding roller, an air classifier for selectively feeding back material to the second high pressure grinding roller, a second high pressure grinding roller for grinding the magnetite, and a dry magnetic separation (DMS) unit for discarding non-magnetic materials, wherein the dry magnetic separation unit is outside the two feedback loops associated with the first and second high pressure grinding rollers.
