Patent ID: 8562204

Claim:
Apparatus for dosed mixing of pourable material components, comprising: a mixing container, two weighing containers, wherein each of the weighing containers comprises a closable discharge opening for discharging content of the weighing container into the mixing container and comprises a weighing device for weighing the content of the weighing container, and several storage containers for respective material components, wherein a weighing container is assigned to each storage container, and wherein each storage container comprises a feeding device for feeding material from the storage container to the weighing container that is assigned to said storage container, and wherein at least two of the feeding devices of respective storage containers are assigned to each weighing container, wherein the mixing container is arranged below the weighing containers such that the weighing containers are simultaneously dischargeable through the discharge openings into the mixing container, wherein the apparatus comprises exactly two weighing containers between the feeding devices and the mixing container, wherein each of the feeding devices comprises a feeding opening for letting the respective material component into the assigned weighing container, which feeding opening is arranged above the respective said weighing container, wherein the weighing containers each have, at a height of a maximal cross-section, a larger dimension in a longitudinal direction than in a direction transverse to the longitudinal direction, and wherein the feeding openings, which are assigned to the respective weighing container, are arranged with an offset from each other in the longitudinal direction above the weighing container, in order that pouring cones emerging below the individual feeding openings have cone tips that are remote from each other, and wherein the two weighing containers are arranged side by side above the mixing container, the longitudinal directions of both weighing containers being arranged parallel to each other, the weighing containers being proximate transverse to the longitudinal direction.
