Source: Babu and Cook; The product of a jaw crusher will have a size distribution such that the -80% fraction size (d80) is slightly less than the open-side setting of the crusher. For example, if the open- side setting is 6 inches, the d80 product size will be 5¾ inches. Source: Unknown; In a hard rock mine,.jaw crusher particle size distribution,© Copyright R P King 2000 TECHNICAL NOTES 5 CRUSHERSJaw 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 . The size distribution of the products tends to be determined primarily by the CSS since no particle can fall through.
