Flat Bottom
The material to be stored in the silo determines the bin floor design. For materials which require fluidizing systems, such as fly ash or cement, flat bottom silos allow air slides to be bolted directly to the bin floor or onto plinths cast into the floor. When columns are needed below the floor, a compromise between the silo designer and the material handling designer takes place to ensure the needs of both are met.
 
Additionally, equipment floors can be designed to accept loads from mixing, conditioning and unloading equipment, if needed.
