vsi crusher reduction rate
Rock Crushing Rule of Thumb
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 by compression]. Roll crusher: feed diameter 1 cm: reduction ratio 5:1 to 10:1; capacity 0.3 to 20 kg/s: Mohs hardness < 7.5.
