Apr 01, 2019 Ideally, the reduction ratio of a jaw crusher should be 61. There are different ways to calculate reduction ratio, but the best way is something called the P80 factor. The reduction ratio is then calculated by comparing the input feed size passing 80 per cent versus the discharge size that passes 80 per cent. Nov 01, 2021 The Symons crusher has proven to be more responsive to the es changes than the Hydrocone crusher (Ruuskanen, 2006). The third option is to control the size reduction by manipulating the crusher feed rate with feeder VFD frequency/speed (Borisson and Syding, 1976, Whiten, 1984, Grujic, 1996, Sbrbaro, 2005).
