May 13, 2019 The reduction ratio is then calculated by comparing the input feed size passing 80 percent versus the discharge size that passes 80 percent. The finer the closed-side setting, the greater the proportion of fines produced. The closed-side setting of a jaw crusher helps determine the nip angle within a chamber, typically 19 to 23 degrees.

Equipment Sizing: Crusher or Grinding Mill

Jul 08, 2016 The 80% passing size in microns is a convenient term for expressing the fineness of a crushed or ground product. It is also a convenient base for calculating the reduction ratio and the work required for reduction. It is readily found by plotting the percent passing on log-log paper, as in Fig. 5, to determine the size distribution curve.
