Water injection system - WIS™
Optimize your grinding process via temperature control
Water injection is one way to control and maintain the cement temperature at mill outlet at a preset level.
Depending on the circuit thermal balance analysis and the mill design, Magotteaux water injection system (WIS™) automatically sprays water into the mills in 3 different ways:
-
1st chamber via its inlet
-
2nd chamber via mill outlet or via mill inlet and intermediate diaphragm (mills with central driving shaft)
- Both chambers if need be for process reasons
Applications
- Cement tube mill temperature management
Specifications
- An hydraulic system entirely fitted in a isolated, modular container (approx. dimension 2.5 m x 3 m x 2.4 m)
- The container has an incorporated heating system to protect against frost damages and a ventilation system to protect against high temperatures
- A water tank
- One (two) pumps with frequency converter(s)
- Water and air distribution pipes
- A spray nozzle spraying the water in the first and/or second mill’s compartment
- A rotary seal (outside of the mill) with wear resistant support for the injection pipe located inside the mill (in case of central driven mill)
- A local electrical cabinet containing the regulation software algorithm
