A method and related apparatus for liberating particles with specific dimensions from a moist Municipal Solid Waste Incinerator ash (MSWI ash) material comprising particles with differing dimensions. In an aspect, the method comprises feeding an amount of the material in a particle stream, striking the particle stream with a striking body to impart a sudden change in direction of the particle stream, receiving at least a part of the stricken particle stream on a moving surface, and transporting the received particle stream to an outlet beyond the receiving area where the particle stream is divided in a first fraction rich of particles of a first group of particle dimensions, and at least a second fraction rich of particles of a second group of particle dimensions, which second fraction is substantially depleted of particles of the first group of particle dimensions.

The embodiments herein provide a centrifugal scattering device having a central axle, a sieve positioned below the central axle, a plurality of rotors, each one having a proximal end and distal end where the proximal end of each rotor is attached to the central axle. The device also preferably includes a guide, angled relative to the central axle and attached to the distal end of each rotor so that the guide travels around the central axle and along the sieve when the central axle rotates.

The invention relates to a pneumatic grain sorter comprising a conduit which has a grain inlet, a first air inlet, a second air inlet, a deflector between the first air inlet and the second air inlet coinciding with the grain inlet, such that the deflector divides the conduit into a first section and a second section, an upper outlet, and a lower outlet, wherein the grain inlet introduces grains into the conduit which are reached by an airflow introduced by the first air inlet into the second section of the conduit, and raises smaller grains to the position of the second air inlet, while larger grains are not raised and they are guided to the first section.

An aggregate processing assembly is provided. The processing assembly includes a separator assembly having a central member extending from a first end to a second end, the central member supporting at least one helical flight provided between the first and second ends, the helical flight having a width provided between a proximal end and a distal end. An assembly housing is provided around a portion of the separator assembly, the assembly housing includes a collection portion for receiving processed feed stock which exits the separator assembly radially away from the central member outward past the distal end, and the collection portion includes a first outlet. A second outlet is coupled to the separator assembly for receiving processed feed stock which exits the separator assembly at the second end of the at least one helical flight. A proppant, an aggregate, a system for processing feed stock to produce a proppant or aggregate, and a method of producing a proppant or aggregate is also provided.
