size in cement grinding mills

  • Cement Kilns: Size Reduction and Grinding

    Rawmill systems typically require a feed of maximum size 5-10 cm, so a crushing stage is first required. In the kiln, the finely-divided rawmix is sintered, resulting in production of hard clinker of typical size 1-50 mm. In order to produce cement, this has to be ground, again to

  • Cement grinding Vertical roller mills versus ball mills

    By these measures it has been possible to obtain particle size distributions for cement ground in OK mills similar to those for cement ground in ball mills (BM), as shown in Figure 6. Figure 6: B It should be noted, however, that operation to achieve a wide particle size distribution (low n-value) has a cost.

  • Calculate and Select Ball Mill Ball Size for Optimum Grinding

    In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize “just in case”. Well, this safety factor can cost you much in recovery and/or mill liner wear and

  • Clinker size and cement grinding GCP Applied

    As a general rule, there should be less than 25% of clinker that is below 1mm in size. Coarse clinker is more of an issue for ball mills. Some cement groups use a formula, such as Bond’s, to calculate the maximum ball size required in a ball mill, based on the average size of the clinker feed.
