Werkwijze voor het scheiden van deeltjes in een vloeibaar medium en een inrichting daarvoor

Particles in a fluid medium are separated by feeding a mixture of particles into a separation chamber. The mixture of particles is treated by moving the medium up and down relative to the mixture of particles. A barrier is present above the mixture to restrain the particles. An Independent claim is also included for an apparatus for separating particles comprising (i) a separation chamber (2), having a supply opening (3) for particles to be separated, (ii) a sieve (4) provided above the supply opening for retention of particles, and (iii) a pump (5) for moving a fluid medium up and down relative to the particles to be separatedCivil Engineering and Geoscience

A method and device for the separation of particles

The invention relates to a method of separating a particle fraction from a particle stream making use of gravitational force and which is performed in a fluid. This provides particle fractions that are collected in respective collecting means. According to the invention the fluid and the collecting means are moved in relation to each other defining a relative direction of movement. There are means provided to limit the movement of the particles to be separated with respect to the fluid in the relative direction of movement. The invention also relates to an apparatus for carrying out the method.Civil Engineering and Geoscience

Method of separating particles in a fluid medium and an apparatus therefor

The invention relates to a method of separating particles in a fluid medium, wherein the particles have a density lower than that of the fluid medium. According to the invention the particles are subjected to an up and down moving flow of the fluid medium, whereby a barrier is present above the particles restraining said particles. It appears that with the method according to the invention a particle separation can be performed in a cost effective and quick manner. The invention is in particular suited for the separation of plastics, such as polyethylene and polypropylene. The invention also relates to an apparatus suitable for performing the method.Civil Engineering and Geoscience
