Abstract
This invention relates to a method for filling particulate material in vertical tubes (1) where the velocity of fall of the material (4) is reduced by having it glide down a rotating spiral duct (2) or by gliding down a rotating inner tube (5) with openings above the bottom (6) through which the material can fall out. The inner tube (5) is filled with the particulate material (4). After the material has fallen out of the spiral duct (2) or the inner tube (5), it can fall towards the tube's (1) wall during the drop onto the top layer of filled material.
