Kiln and mill
If bearing and shell cooling stops, the equipment overheats.
For your sector
Water Treatment in a Cement Plant
In a cement plant, water cools the kiln, the mill and the waste-heat boiler. Dust and hardness make this water hard to manage.
Scale in a cooling tower · Scale in a steam boiler · Corrosion in a closed loop
Where the water is used
Cooling tower
Evaporation raises hardness. Dust sticks to the fill.
Closed loop
The closed cooling circuit of heavy equipment replaces little water. Corrosion and sludge block a narrow passage.
Waste-heat boiler
Heat in the kiln gas makes steam. Scale in the boiler water lowers heat transfer.
Risks specific to this sector
Dusty make-up water
Yard dust enters the make-up water and the tower. Suspended solids stick to the hot surface.
High hardness
When hard water evaporates, scale forms faster in the tower and in the boiler.
Fill blockage
Dust and scale close the fill together. The tower cannot reject heat.
Waste-heat boiler
A scale layer does not pass the gas heat into the water. Steam falls, and the gas side works harder.
What damage does it cause?
Signs
- Tower water turns cloudy, or dust and scale are visible on the fill.
- Kiln or mill bearing temperature rises.
- The waste-heat boiler cannot make the same steam from the same heat input.
- Closed-loop water turns red-brown, or the flow falls.
How do you solve it?
Tower program
The scale and corrosion chemical and the dispersant work together. Dust does not leave with a scale inhibitor alone.
Hardness checks
Read the hardness of the make-up water and the tower water on a regular schedule. Open blowdown from this data.
Closed loop
Put a corrosion inhibitor in the equipment circuit. If the water turns brown, flush it first.
Waste-heat boiler
Select the boiler chemical and the blowdown from the feed water analysis.
Our related products
The tower chemical, the dispersant, the closed loop and the waste-heat boiler are separate jobs. The dosage is set from the water analysis.

Frequently asked questions
How do you manage dust and scale together in a cement tower?
Ck 220 decreases the scale and corrosion risk in the tower. Ck 180 prevents suspended particles and sludge from sticking to the surface. Select the two together. Set blowdown from hardness and conductivity.
Which product is used for the waste-heat boiler?
Cefopol 1040 prevents scaling in the steam boiler and protects the metal against corrosion. The product is NSF approved. The exact choice depends on the feed water analysis.
What do you need if mill cooling is a closed loop?
Ck 13 protects the copper surface in closed-loop heating and cooling. If the water turns brown, remove the collected dirt first, then put the inhibitor in service.
What sets the dosage?
The dosage is set from the make-up water and the tower water analysis. Hardness, suspended solids and conductivity are read together.
