  • Patent number: 10751723
    Abstract: 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.
