Sorting apparatus for sorting of bulk material comprising flowable particles, the apparatus comprising: a material feeding chamber for receiving and/or holding bulk material; a feeding aperture positioned relative to the chamber for allowing material particles to flow out of the material feeding chamber under gravity; a slanted receiving surface positioned below the feeding chamber and spaced away from an edge portion of the feeding aperture to receive the material particles flowing out from the feeding aperture; wherein a gap between the edge portion of the feeding aperture and the slanted surface is at least equal to the average particle size of the flowable material particles being sorted.
