FDSP Hopper Buttom Silo System

Hopper bottom steel silo are famous for its automatic discharging process. 

The grain inside silos could unload automatically due to gravity, and very efficient; 1.The steel legs are made of H beam which have good quality and bearing. 

2.2 kinds of angle-45 degree and 60 degree, among which the 60 degree conical-bottom is usually used to store larger pellet and powdered materials of high viscosity. 

3.Hot dip galvanized steel sheets, 275g/m2 coating galvanizing. 

4.Bolt and screw connected, assembly and easy maintenance.

  • Raw Material Receiving Section: Feeding by truck discharge, manual dumping, or railway etc.


  • The Cleaning System: drum cleaner machine or vibrating cleaner machine, for removing impurites from the grains, like stone, straw, etc. 

  • The Drying System: decrease the extra moisture of grain.

  • The Storage System (Ventilation System, Level System, Temperature Monitoring System)

----- Flat Bottom Steel Silo
