Abstract Tianjin Cement Industry Design & Research Institute Co., Ltd. developed the N-U shape classifier which use the newest shape blade, it can control the particle size distribution of product by changing the blade angle and classifier efficiency. The classifier of raw mill in Hebei QianBao Special Cement Co., Ltd. is modificated to N-U shape classifier. It shows that feeder of VRM increase 18.7%, the system power consumption of raw mill decrease about 5.0kWh/t, the payback cycle is only one year. The remarkable effect of N-U shape classifier application made a foundation for raw mill modification in the future.
