Separation-apparatus

摘要

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.

1. 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, wherein the particle-stream is a moist stream of particles sized in the range of 0-15 mm, 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 infeed-device comprises a vibrating plate having an edge positioned above the drum, which edge is embodied as an outlet for the particle-stream, the infeed-device further comprising a slide-plate immediately adjacent to said edge that tilts downwards as seen from the edge, the slide-plate being inclined at an angle in the range 70-90 deg. with respect to the horizon, the vibrating plate and the slide plate cooperating to cause in use a mono-layer type flow of the particle stream comprising a plurality of particles across a width of the particle stream, and the edge of the vibrating plate being positioned vertically or near-vertically above an axis of rotation of said drum so as to cause that in use the particles of the particle-stream fall towards the drum in a direction aimed towards said axis of rotation or its immediate vicinity, and such that the plates of the drum impinge on said falling particles at a moment that said plates are in a vertically or near- vertically upwards oriented position extending from the drum.
