Feb 17, 2017 According to this, if we now further crush down to diameter z the additional work done is Q (1/z – 1/y), and the total work done in crushing from diameter x to diameter z = Q (1/y – 1/x) + Q (1/z – 1/y), which = Q (1/z – 1/x), the same as if the crushing were all done in one operation. To make the computation, then, it is necessary to determine the reciprocal of the diameter of the particle.
