The invention relates to a bulk material silo and method operating such silo, the silo being provided with a central discharge chamber from which a venting channel leads to the peripheral wall of the silo, the side walls of the channel having openings of the material to enter. Such a silo construction ensures a symmetrical material supply to the discharge chamber over the entire periphery.

Silo for storing and discharging bulk material and method of operating

A silo for loose material in powder form having a base provided with a central conical section projecting upwards to form an annular discharge zone having floor portions inclined in a direction leading to an opening in a discharge chamber and in such manner that the material flows approximately tangentially towards the material discharge openings.

Silo for loose material in powder form

A method and apparatus for mixing fine material in which material is extracted from a level located above the cover of a discharge chamber at the base of a mixing silo and returned to the upper part of the silo. Fresh material is delivered to the upper part of the silo, and in a region that is radially inward of that in which the extracted material is returned.

Method and apparatus for mixing fine material

The invention relates to a storage and mixing silo for bulk material comprising a mixing compartment in the form of an annular chamber. The radial width and the height of the chamber are proportioned to the diameter of the silo, the chamber has a material inlet opening and a material outlet opening circumferentially spaced from one another, and the chamber has a plurality of independently aeratable zones.
