Abstract

A conveying apparatus characterised by a distribution plate (10) having a plurality of apertures (12) therein whereby a fluid can flow through the plate, a conveying zone (22) disposed above said distribution plate (10) and fluid supply means for supplying a fluid to said conveying zone (22) through the distribution plate (10), wherein said distribution plate (10) is adapted to direct the fluid therethrough in a direction which has a component extending along a surface (14) of the plate, whereby a material disposed in the conveying zone is fluidised and is conveyed along said surface of the plate.
