• Iron ore crushing and screening process

     · The fine jaw crusher is generally used for small iron ore dressing fields, and its equipment value is low, the structure is simple, and the maintenance is simple and convenient. However, the discharge port of the fine jaw crusher can only be adjusted to a minimum of 25mm, so the crushing particle size is generally below 40mm.

  • Modelling the size of the crushed zone around a blasthole

     · The function obtained by nonlinear regression is given by (10) r o r c = (CZI) − or (11) r c = o (CZI), where CZI is defined as the crushing zone index. This is a dimensionless index that identifies the crushing potential of a charged blasthole. The correlation coefficient of the relationship given by Eq. (10) is R2 =

    predicted amount of fine material in wellgraded m uckpiles, when n is small. It has gradually become clear that very few sieved fragment size distributions follow Equation (1), especially in the fines range. The JKMRC has come up with two models that address this problem Ð the crush zone model9 (CZM) and the twocomponent model 7 (TCM). In the CZM, the fragment size .
