Abstract
The invention relates to a pneumatic mixing silo comprising a storage compartment, a central mixing compartment connected thereto and at least one material inlet opening into the mixing compartment and at least one material outlet connected to the mixing compartment. A considerable improvement in the mixing effect of this mixing silo (1) may be obtained above all if the material outlet (14) is formed by an overflow from the mixing compartment (3). In addition, correcting material may be directly introduced into the mixing compartment through an additional material inlet (12).
