CONTAINER, DEVICE AND METHOD FOR STORING OR PROCESSING PARTICULATE MATERIALS TO MINIMIZE OR ELIMINATE VIBRATIONS SUCH AS QUAKING OR SHAKING

摘要

The invention provides containers with lower vibrations, such as quaking and shaking as well as noise effects, known also as hooting, honking or howling, and an effective and cost-competitive method and device to decrease such phenomena during the discharge of granular material particles from silos, hoppers, bins, reactors and in general containers for storing or processing such granular material particles. The invention comprises at least one baffle that is attached to the container wall, in the lower portion or at the bottom of the tapered discharge part of said container, protruding towards the central axis of its tapered discharge part. The baffle forms a stagnant zone in the bed of the granular material particles in contact with the container wall whereby the particles in that zone flow under the friction against other particles instead of the friction between the particles and the wall.
