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.
