Therefore, if a foundation allowing settlement is used, a single-point discharge system is required to prevent uneven loading within the storage, along with the establishment of an emergency discharge channel and system. If a rigid non-settling foundation is employed, a multi-point, multi-corridor discharge system can be used, and a clearing channel should also be provided. In any discharge method, gravity-assisted self-flow should be the primary method, to reduce energy consumption and maintenance costs, with pneumatic fluidization discharge as a secondary method.

The silo design should allow for sufficient safety margin, and fatigue calculations for temperature stress and pressure changes in the incoming and outgoing materials should be conducted. Stability and strength requirements of the silo under the extreme condition of material tilt must be considered. The silo should be designed to withstand a certain degree of micro-negative pressure, greater snow load, greater wind load, and storage of materials with tilt, as these four loads act together — only then can it be considered safe.

In normal circumstances, the balance of air pressure prevents the storage area from exceeding negative pressure levels. However, due to potential malfunctions in the air pressure balancing system, which can be difficult to detect in time, even with a detection alarm system, there's a possibility of temporary malfunction post-activation, which could lead to accidents. Therefore, the design should be based on the most adverse load combinations.
