The challenge
The silo discharge base takes the full abrasive load of the material and the structural load of the silo above. Worn chutes, damaged liners and fatigued supports were limiting discharge and threatening the structure.
All demolition and heavy welding had to be done from inside the silo, a confined space with hot work.
Scope of works
- Confined space entry with permits, gas monitoring, ventilation and standby rescue
- Controlled removal of worn discharge chutes, liners and supports
- Installation and structural welding of a reinforced steel cone, brackets and new discharge equipment
- NDT inspection of welds and alignment checks
Outcome
The silo base was fully upgraded, restoring reliable discharge and extending the life of the silo. Discharge problems are often solved by redesign rather than force, as in our cement silo unblocking case study. See also our silo services.
