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 (20), striking the particle stream with a striking body (3) 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 (6), and transporting the received particle stream to an outlet beyond the receiving area where the particle stream is divided in a first fraction (40) rich of particles of a first group of particle dimensions, and at least a second fraction (60) 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.

Abstract

The invention relates to a separation-apparatus for separating from a particle-stream at least a first fraction with particles of a first group of dimensions, and a second fraction with particles of a second group of dimensions, comprising an infeed-device for the particle-stream, a rotatable drum having at its circumference plates, each plate having a radially extending hitting surface for the particles, at least a first receiving area proximal to the drum for receipt therein of particles of the first fraction, and at least a second receiving area distant from the drum for receipt therein of particles of the second fraction, wherein the apparatus has a housing so as to protect the particles from outside weather-conditions, allowing that the particles of the particle-stream to be processed by said apparatus have dimensions in the range 0-15 mm.
