Jul 23 2021· This is because the primary jaw crusher with an ideal reduction ratio of 4 will crush and reduce the minus 500mm feed material to output material of minus 125mm. In turn the secondary cone crusher similarly with an ideal reduction of 4 will be fed with this minus 125mm material and produce an output of minus 32mm end products.
Jaw 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 that
Jaw crushers offer reduction ratios of up to about 61 while cone crushers can reduce material size up to a maximum of 81 ratio. The finer the crushing the smaller the reduction ratio.
