“Computer Aided Design of Jaw crusher”

Jaw crusher movement is guided by pivoting one end of the swinging jaw and an eccentric motion located at the opposite end [4] The size of a jaw crusher is designated by the rectangular or square opening at the top of the jaws For instance, a 22 x 30 jaw crusher has an opening of 22" by 30", a 46 x 46 jaw crusher has a opening of 46" square

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 openside set (OSS) is specified This reflects the fact that considerable portions of the processed material fall through
