Grinding Kinetics Of Slag And Effect Of

This study aims to model grinding of a Polish ferronickel slag and evaluate the particle size distributions PSDs of the products obtained after different grinding times. Then, selected products were alkali activated in order to investigate the effect of particle size on the compressive strength of the produced alkali activated materials AAMs.

  • A Study Of Intergrinding And Separate Grinding Of Blast

    With the use of these parameters, grinding rate curves for slag and clinker were extrapolated as seen in Fig. 5, which indicates that slag would have lower rate below approximately 650 m. This explains why slag has an overall lower grindability although it needs experimental verification of grinding rates for these fine sizes below 650 m.

  • Effect Of Fine Grinding On The Properties Of Alkali

    slag in alkali activation was studied by the authors and promising results for ladle slag as a sole binder obtained2. Based on the hydration kinetics, it is apparent that slag made up of finely distributed particles reacts faster than coarse particles due to the high specific surface area of the former. Therefore, in this study the effect of
