A Silo Is A Container For Storing Materials, Usually Of Steel Structure Or Reinforced Concrete Structure. Geometry Of Silo: The Upper Part Is Mostly Cylindrical Or Prismatic. The Lower Part Shrinks Into A Victoria Shaped Funnel With A Discharge Opening. The Materials In The Warehouse Are Unloaded And Transferred From The Bottom Discharge Port By Their Own Weight. The Overhead Silo Entrance Reduces The Floor Area And Makes Full Use Of The Space. Usually, Belt Conveyor Is Used To Feed Materials From The Top Of The Silo For Storage, And Vehicles Or Belt Conveyors Are Used To Transfer Materials From The Discharge Opening; Overhead Cableway Can Also Be Used For Loading And Unloading Of Pit Mouth Silo. The Elevated Silos Can Be Set Separately, Or Several Single Silos Can Be Formed Into A Group. The Elevated Silo Has A Trend Towards Large-Scale Development. The Diameter Of The Cylindrical Silo Has Reached 30m, And The Height Diameter Ratio Is Greater Than 2.5. Japan'S Coal Storage Steel Silos Have A Capacity Of 80000 Tons. China'S Single Warehouse Capacity Has Exceeded 10000 Tons.
The Shallow Silo With The Height Less Than The Width Is Called The Chute, Where The Horizontal Section Is Long And The Bottom Is Contracted Into A Long Slot As The Discharge Opening. The Material Trough Has Elevated, Underground, Semi Underground, Etc. Vehicles Are Used To Feed From The Upper Opening Of The Material Trough And Unload From The Lower Opening Of The Material Trough To The Belt Conveyor For Transfer. Measures Such As Moisture-Proof, Dust Removal And Ventilation Shall Be Taken For The Underground Material Trough To Improve The Operating Conditions.
Discharge Hopper Is A Small Volume Silo Used To Transfer Or Guide The Flow Direction Of Bulk Materials. The Funnel Can Have No Cylindrical Part But Only A Conical Part, Or The Cylindrical Part Is Very Short, Mainly Playing The Role Of Transfer And Unloading.
