Abstract
The dosing device is installed between a funnel-shaped storage container for the pulverulent material and an open vessel underneath it. It consists of a flat plate arranged between the open vessel and the outlet aperture of the storage container so that a standing column of material is formed between this plate and the outlet aperture, and a dosing rod which is displaceable or rotatable in a horizontal plane. The dosing rod is passed periodically through the column of substance and with each passage conveys an approximately constant quantity of material into the vessel underneath it. This device is also capable of dosing materials which tend to stick together and cake to the apparatus.
