Cement mill roller reclamation process

The coarse part is returned to the roller press for crushing once again; the medium fine part is sent to the ball mill for final grinding; and the fine part is discharged directly as the finished product cement. Because the roller press and the ball mill are two separate circulate system, the whole cement grinding process is easy to operate and control
