Cement Plant 40 m Silo Cleaning Works No. 15 & No. 16

Cleaning works in two 40 m cement silos, No. 15 and No. 16, to remove caked material and restore flow.

The challenge

Caked material on the walls and cone of silos No. 15 and No. 16 was reducing capacity and disrupting discharge. At 40 m deep, any hang-up of material is a serious engulfment risk.

The silos had to be cleaned safely and returned to service in a planned window.

Scope of works

Isolation of the silo and confined space permits with continuous gas monitoring
Rope access descent and top-down cleaning of walls and cone
Removal of caked deposits, bridges and rat-holes
Inspection of the silo interior after cleaning

Outcome

Silos No. 15 and No. 16 were cleaned and handed back with restored capacity. Read how flow can be restored when a silo is fully blocked in our cement silo unblocking case study, or see our silo cleaning services.
