Cement Plant 40 m Clinker Silo Cleaning Works No. 1 & No. 2

The challenge

Clinker is abrasive and, with moisture, forms hard build-up on silo walls. In tall 40 m clinker silos, these deposits reduce usable capacity, cause bridging and rat-holing and can collapse without warning.

Cleaning silos No. 1 and No. 2 meant working against heavy deposits in a deep confined space.

Scope of works

• Confined space entry with permits, gas monitoring, ventilation and standby rescue
• Rope access from the silo roof, working top-down so no one is below unstable material
• Breakout of hardened clinker with pneumatic tools and lances
• Controlled discharge and removal of the material

Outcome

Both silos were cleaned and returned to full capacity with free discharge. Learn more about our silo cleaning and material flow restoration.
