Cement grinding Vertical roller mills versus ball mills. patent and started selling an improved version of this mill all over the world For the cement industry the ball mill was really an epoch making breakthrough as for almost 80 years it was the predominant mill for grinding of raw materials and coal and still today is the most used mill for cement grinding
Operational factors to monitor for optimal hammermill performance include the raw material feedrate, fan or blower performance and the differential pressure across the AMS. The hammermill's inlet and outlet temperatures, drive motor amperage, and the mill's inlet and discharge differential pressure are also important to monitor.
The power consumption of its grinding system is about 20%-30% lower than that of the ball mill, and this power saving effect is more obvious with the increase of raw material moisture. In addition, the vertical mill adopts a fully enclosed system, which works under negative pressure, without dust, and has a clean environment.
