Abstract
A sieving device comprises a sieve with an electrical linear device mounted in spaced apart relation from the mesh of the sieve. Particles supplied to the side of the mesh away from the thrust device are caused by the thrust device to move across the mesh and those which are smaller than the mesh pass through the mesh and towards the thrust device. Conveniently a plate is disposed between the mesh and the plate. Particles passing through the mesh then come into contact with the plate and move along it under the influence of the thrust device.
