Gyratory Crusher an overview ScienceDirect Topics
Similar to jaw crushers, the mechanism of size reduction in gyratory crushers is primarily by the compressive action of two pieces of steel against the rock As the distance between the two plates decreases continuous size reduction takes place Gyratory crushers tolerate a variety of shapes of feed particles, including slabby rock, which are not readily accepted in jaw crushers

2 GYRATORY CRUSHERS
the basic gyratory crusher was developed prior to World War I The improvement of the internal combustion engine and use of pneumatic tires created a new set operating wnditions Early mines were small, using shrinkage stoping and small mine can The capacity of material handling was small, limiting the size largest piece and the feed rate Improved material handling resulted in
Gyratory Crushers Mineral Processing Metallurgy
17/02/2016 The action of the gyratory crusher, ranges of reduction sizes, and types of equipment, made it possible to establish a consistent common factor known as the Work Index for accurately determining the power required for crushing In the Work Index method, frequently referred to as the Bond method, the Work Index is actually the total work input in kwhr per
Industrial Solutions Gyratory crushers
Jaw gyratory crushers can handle much bigger chunks of material than comparable gyratory crushers of the same mantle diameter Jaw gyratory crushers feature a higher crushing ratio and less tendency to become clogged in the feed zone as a result of bridging Jaw gyratory crusher Weights 1) Type Feed opening Mantle diameter (oversized) Speed of eccentric
TECHNICAL NOTES 5 CRUSHERS mineraltech
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 the crusher at OSS and this determines the characteristics

HighSpeed Gyratory Crushing > Fine Cone Crushers
22/11/2015 Below you see a gyratory reduction crusher, which introduced the cylindrical top shell, flared head, and reversible concaves Even with the older style of straight concaves, with which this machine was originally fitted, it represented a distinct step forward in secondary crusher design, and the later introduction of nonchoking concaves increased its efficiency
Crusher Reduction Ratio Mineral Processing Metallurgy
12/01/2016 As an example, suppose that it is required to make a reduction of 7:1 in two stages of crushers, one a standard gyratory and the other a finereduction crusher We know from our examination of the crushing characteristics of these types that, for equal reduction ratios, the volumereductionratio in the standard gyratory is considerably higher than it is in the fine
