  • (PDF) SIZE REDUCTION BY GRINDING METHODS

    Grinding mills – Reduction ratios All crushers including impactors have lim ited reduction ratios Due to the design there is a restricting inWe can use the app linked above to get the number of milling stages, by inserting the correct values, the total reduction ratio, feed size in mm In the example we get 4 stages, 3 crushing stages + 1 grinding stage You can use a jaw crusher of 3/1 followed by a cone crusher 5/1, a second cone crusher 8/1, and a rod mill of 67/1 reduction ratioCalculate the Reduction Ratio and the Number of Millingreduction ratio of rod mill – Grinding Mill China This indicates that the rod mill reduction ratio is much larger than those at normal condition, and ballREDUCTION RATIO FOR BALL MILLING | Crusher Mills,
