Rock Crushing Rule of Thumb
Jaw crusher: feed diameter 0.1 to 1.5m; reduction ratio 5:1 to 10:1; capacity 1 to 300kg/s; Mohs hardness < 9 [reduction by compression]. Gyratory crusher: feed diameter 0.75 to 1.5m; reduction ratio 5:1 to 10:1, usually 8:1; capacity 140 to 1000 kg/s; Mohs hardness <9. More suitable for slabby feeds than jaw crusher. [reduction …
Factors to Consider When Selecting the Proper Roll Crusher …
When taking this into account, you must also refer back to the feed size to see if the ratio of reduction requires multiple stages of crushing. A good rule of thumb for single-stage crushers is that a Single Roll Crusher provides up to a 6:1 ratio of reduction and a Double Roll Crusher provides up to a 4:1 ratio of reduction.
