| 摘要 |
<p>The invention relates to a device for extracting a product in the divided state, stored in a silo (10), and for volumetric dosing of this powdered or granular product. It includes, inside the said converging lower part (12) of the silo, unbridging means; a decompression chamber (14) arranged in the lower part of the said silo and whose diameter is greater than that of the terminal section of the said converging part of the silo, an assembly (16) for entraining the said product in a direction which is substantially perpendicular to the axis of the silo which communicates with the lower end of the decompression chamber and means (58), for holding the said entrainment assembly in charge (under control) during flowing of the divided product, arranged in the zone where the said decompression chamber emerges in the entrainment means. <IMAGE></p> |
