Abstract

See full text

An apparatus for adding a first granular material which is disposed in a first container to a second granular material is provided and includes a conveyor conduit connected to a conveyor means, and a feed conduit communicating with the conveyor conduit for the feed of the first granular material which is to be added. In order to be able more easily to mix substances in powder or granular form, wherein the mixing ratio is to be continuously adjustable, the invention provides that disposed below the outlet opening of the first container containing the granular material to be added is a gap which is formed between two rollers. A communicating passage is provided between the gap and the feed conduit to provide the first granular material. By varying the width of the gap, the amount of the first granular material added may be quantitatively controlled.
