    All crushers have a limited reduction ratio m eaning that size reduction will take place until the material is smaller than the set crush ing size The feed cavity ofJaw crushers are operated to produce a size reduction ratio between 4:1 and 9:1 Gyratory crushers can produce size reduction ratios over a somewhat larger range of 3:1 to 10:1 The primary operating variable available on a crusher is the set and on jaw and gyratory the openside set (OSS) is specified This reflects the fact thatTECHNICAL NOTES 5 CRUSHERS mineraltechThe 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 closedside setting, the greater the proportion of fines produced The closedside setting of a jaw crusher helps determine the nip angle within a chamber, typically 19 to 23 degreesTips to maximize crushing efficiency Pit & Quarry : Pit
