Exploring Jaw Crusher Efficiency | Kemper Equipment
Jaw Crusher Reduction Ratio. Either an 8-to-1 or 6-to-1 ratio should be the target reduction ratio for maximum jaw crusher efficiency. This setting typically provides an ideal P80 factor—when 80% of crushed material produced by primary crushing will pass screening after processing. A smaller closed-side setting will produce more fines.
