Abstract：Aiming at the problems of unsatisfactory cement particle size distribution,high water demand,and poor fluidity in the cement roller press finish grinding system caused by insufficient classification accuracy,a special multi-rotor high-efficiency classifier adapted to the system has been developed.This equipment adopts three or more independently adjustable rotors,enabling precise control and optimization of the particle size distribution of finished cement through flexible adjustment of rotational speed,rotation direction,and structural parameters.Multiple engineering application cases show that this classifier,can optimize the particle size of cement produced by the roller press final grinding system to an ideal state,achieving a significant reduction in system power consumption while maintaining key performance indicators comparable to those of the combined grinding system.Furthermore,the roller press final grinding system equipped with this classifier supports flexible switching among finish grinding,semi-finish grinding,and combined grinding production modes.It achieves the dual goals of energy saving,consumption reduction,and flexible production.
