ABSTRACT:
A particle filling line comprises a vertically-oriented conduit that includes a conduit hollow. The conduit includes a conduit top and a conduit bottom. The conduit bottom defines an outlet. The conduit is arranged so that particles supplied to the conduit top flow through the outlet to be received by one or more containers disposed on a movable conveyor belt. The conduit hollow includes one or more conduit hollow elements disposed therein. The one or more conduit hollow elements include any of a plurality of agitators and an auger. The particle filling line is arranged for determining a resistance that is based on the spacing between the one or more conduit hollow elements and the conduit inner walls. When the resistance is determined to be less than a threshold resistance value, the particle filling process ceases.
