    distribution? Empirical evidence obtained by the author, using a laboratory crusher, suggests that when a crusher is fed at a very alow rate, the resulting size distribution is essentially normal, but skewed slightly towards the fines. The mean size tends to be somewhat larger thsn the gap setting (by about one standard deviation).

  • Rock Crushing Rule of Thumb - Mineral Processing & Metallurgy

    Nearly all crushers produce a product that is 40% finer than one-half the crusher setting. Source: Babu and Cook; The product of a jaw crusher will have a size distribution such that the -80% fraction size (d80) is slightly less than the open-side setting of the crusher. For example, if the open- side setting is 6 inches, the d80 product size ...

    Weibull distribution model for the first time when studying the particle size distribution of coal. A Weibull distribution model that describes the particle size distribution obtained from impact crushing of a granite single particle can be expressed as: [1] where R(d) is the cumulative mass percentage of particles d in size after crushing.

  • Control oriented modeling of flow and size distribution in ...

    A dynamic cone crusher model that describes the output size distribution (size reduction), and the flow was presented in this work. Simulations have showed that the steady-state model behavior is qualitatively consistent with measured crusher behavior, as reported in e.g. ( Lee and Evertsson, 2011 ), in terms of response to changing the ...
