Description

is, closes the opening 11 to the outside or releases it. The premixer is expediently so high on the feet 4 that its discharge channel 13 comes over the upper edge of an elevator container 14 of the device when the elevator container 14 is in its lowest position. As the mixing tool in the mixing vessel 1 the mixing disk 10 is used, the edges 16 α upwardly and the edges 16 may be angled downward.

The rotatability of the premixer is necessary so that the discharge channel 13 over the upper edge of the Elevator container 14 comes after this has come into the receiving position.

The guide of the elevator container 14 can, however, also be designed so that it is in its last part leads laterally under the discharge channel 13 of the premixer. The premixer must be next to the elevator container 14 because the space in front of the elevator container must remain free for loading with the other aggregates. In addition, the elevator container 14 often leads under in mixing plants the metering wall and can no longer be charged with the mixture from the premixer from the front.

A partition 17 creates a separate chamber 18 in the elevator container 14 for the mixture. Since the mixture is always thin, it first flows into the elevator container 14 when it is tilted the main mixer. The aggregates then come evenly into this mixture. A covered and angled outlet 19 in the elevator container 14 can preferably contain the mixture bring about in the middle of the elevator container 14 to flow out.
