Clinker is stored hot, and that is the whole problem. Material that goes in above ambient carries residual heat and moisture into the silo, and where the two meet the wall, it hydrates and sets. Over a campaign the coating thickens until the silo is quietly holding a fraction of what its level indicator claims.
The capacity you are actually running. A clinker silo with 300 mm of coating on the wall has lost far more volume than the number suggests — capacity falls with the square of the radius. Plants routinely discover they have been operating a nominal 20,000 T silo at closer to 15,000 T for years.
Whipping for the wall coating. The boom enters through the top hatch and the whipsets clean the coating off progressively, working down as the silo empties. The whipset is chosen for the state of the liner, not just the hardness of the clinker — on a worn vessel that matters more than raw impact.
Cardox CO2 for the cone, the outlet and the extraction gates. This is where clinker sets beyond anything mechanical will move. A tube fired through a wall socket delivers a controlled heave, regulated between 1,200 and 3,000 bar to suit the vessel and its refractory, and breaks the mass in milliseconds.
Sockets pay for themselves on clinker silos. Because the coating returns over a campaign, a silo fitted with permanent sockets can be cleared repeatedly without an outage — the tube goes in, the material moves, and the plant keeps running.
Clinker silo work usually pairs with the rest of the pyro line — extraction gates, chutes and conveying line blockages, and, where the kiln is down anyway, ring build-up, preheater and cyclone clearing.
Send the vessel size, the material and how long it has been a problem. We will come back with an approach, a duration and a price.
