Crusher Reduction Ratio - Mineral Processing Metallurgy

19/03/2017  This is like saying that, as the Crusher Reduction Ratio in any given crusher is increased, the % of fines in the product will increase, even though the discharge setting remains unchanged. Both of these statements are true, but the degree to which the product is affected depends to a much greater extent upon the ratio-of-volume-reduction in the crusher chamber than it does upon the actual ...

TECHNICAL NOTES 5 CRUSHERS - Mineral Tech

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 open-side set (OSS) is specified. This reflects the fact that considerable portions of the processed material fall through ...

Jaw Crusher - ScienceDirect

01/01/2016  The reduction tonnage term is dependent on the properties of the material crushed so that for a given reduction ratio, the crusher capacity will vary for different materials. Taggart attempted to compensate for this by introducing the comparative reduction tonne, Q RC, which is related to the reduction tonne by the expression (4.23) Q R = K Q RC. The comparative reduction tonne is a

Gyratory Crusher - an overview ScienceDirect Topics

Generally, jaw and impact crushers exhibit a large reduction factor, defined as the ratio of the particle size of the input to that of the output material. A jaw crusher crushes only a small proportion of the original aggregate particles but an impact crusher crushes mortar and aggregate particles alike and thus generates a higher amount of fine material ( O’Mahony, 1990 ).
