Grate Cooler
For the cement clinker cooling scenario, INVT provides a coordinated electric control solution to ensure efficient cooling and stable operation of the grate cooler.
For the cement clinker cooling scenario, INVT provides a coordinated electric control solution to ensure efficient cooling and stable operation of the grate cooler.
Uneven operation of the grate bed, poor cooling effect
Poor linkage between the fan and the grate bed, high energy consumption
Difficult fault early warning, frequent sudden shutdowns
With GD series inverters as the core, INVT controls the grate cooler group, realizes coordinated adjustment of grate bed speed and air volume combined with temperature feedback, and monitors equipment temperature to early warn of faults in advance.
Core Concept
Coordinated electric control + temperature feedback to realize linkage between the grate bed and the fan and ensure efficient cooling.
Technical Proposition
Coordinated control: GD series inverters are used to control the grate cooler group, and coordinated adjustment of grate bed speed and air volume is realized combined with temperature feedback.
Multi-machine synchronization: Multi-machine bus coordinated control compensates for load fluctuations and ensures uniform clinker cooling.
Fault early warning: Timely alarm when key parameters are abnormal to reduce unplanned downtime.
Adjust cooling air volume on demand to reduce invalid energy consumption and operation cost.
Multi-machine bus coordinated control compensates load fluctuation and ensures uniform clinker cooling.
Starting current reduced to 1.2–1.5 times rated value, easing impact on motor and grid and extending life.
Integrated status monitoring, real-time feedback of speed/current, fault warning and simplified maintenance.
