Abstract (en)
[origin: WO9700124A1] The invention relates to a method and an apparatus for homogenizing bulk material, wherein the bulk material is supplied from above into a container which is restricted sidewards and downwards and is fed out by means of a feeding out conveyor located in the lower portion of the container. The characteristic features of the invention are that the bulk material is fed in from above in one end of the container (20), wherein the bulk material is caused to slide down towards the opposite end of the container such that a bed of bulk material is formed having a sloping profile in the container, and wherein, due to the sliding, heavier and/or coarser fractions of the bulk material slide more than lighter fractions, and that during each time unit a volume of bulk material is fed out from the bottom portion of the container from each section ( DELTA 1) of the length of the container in the feeding out direction, said volume of bulk material corresponding to the supply of bulk material during the same time unit to the section (An) of the upper surface of the bed lying straight above said section of the length of the container, wherein the bulk material is caused to move essentially downwards in the bed along the entire length of the bed towards said outfeeder (30) which feeds out the material from each section at essentially the same rate as new material is supplied to the above lying surface section of the upper surface of the bed.
