Abstract: A vibrating device, the vibrating part of which is equipped with a plurality of intercoupled unbalanced, shafts rotatably driven, in which the centrifugal forces generated neutralize one another in the direction at right angles to the direction of vibration and have the same directions in the direction of vibration, wherein the central shaft is provided on both sides whereof unbalanced shafts are located.

Abstract: A method and device for separating particles suspended in a liquid by guiding these particles through a bed of balls of ferro magnetic material and by moving these balls together with the particles through a magnetic field, by supplying a washing liquid during the passage of the particles through the magnetic field for washing off the non-magnetic particles and by supplying a liquid outside the magnetic field for discharging the magnetizable particles. After leaving the magnetic field the balls and the magnetizable particles fall freely over some distance.
