| Granular materials or bulk solids are usually stored in silos. These structures are used in many industrial sectors (chemical, agricultural, food, mining, etc.) and can vary in size from the smallest ones containing about ten tonnes to the largest ones containing sometimes several hundred thousands of tonnes. The first question posed when a silo installation is designed is: What type of material is going to be handled?. The handling characteristics of the different materials stored require different approaches for the design and construction of successful economical installations. Solids are characterized according to their mechanical properties so that their understanding is crucial to explain the phenomena that occur inside these facilities. Dilantacy, rigidity and deformability of the material, adhesion to the wall and cohesion or its internal resistance, may explain in some cases the different load distribution patterns along the silo wall, slip-stick effect, generation of rupture planes, blockages during discharge and so on. Pressure measurements in a test silo installation at the Universidad Politécnica de Madrid have been interpreted, and explanations to the phenomena observed during filling and discharge have been mainly found in the mechanical behaviour of the granular solids stored. Moreover, explanations to the granular effects arisen from local imperfections introduced in the silo wall have been also provided by using a discrete element method. | |
