Cone-bottom silos can meet the requirements of first-in-first-out of materials to a certain extent, but when there are fewer materials, the law of material flow is funnel flow, the material in the middle will flow down first, and the material close to the silo wall will be affected by the friction and adsorption of the silo wall and will be retained in the silo; as the material is continuously loaded, the pressure at the bottom of the silo will become greater and greater, especially the cone bottom section is affected by the splitting effect, the extrusion force is greater, and the material compaction and arching phenomena often occur.
