Abstract

The invention relates to a device for dosing and mixing powdery materials, said device comprising essentially horizontally adjacently arranged reservoirs for the starting materials, provided with a closing and dosing cap (27) on the lower side, dosing devices (12) for dosing the materials, and at least one mixing device (10) for mixing the dosed materials. At least one charge container (2) comprising a lid (13) on the upper side thereof and used to receive dosed quantities of initial materials is displaceably t-arranged beneath the reservoirs, the charge containers (2) being provided with a flap (14) on the lower side thereof. The aim of the invention is to create one such dosing and mixing device which is as flexible, expandable, and structurally simple as possible. To this ON end, the reservoirs are embodied as dosing containers (1) with integrated dosing devices (12). The invention also relates to a device for dosing powdery materials, comprising a reservoir provided with a closing and dosing flap (27) on the lower side, and dosing devices (12) for dosing the materials, the reservoirs being embodied as dosing containers (1) with integrated dosing devices (12).
