Besides, gyratory crusher is heavy than jaw crusher, its not convenient to move. Capacity Gyratory crusher can work continuously, has high productivity and crushing ratio ( up to 69.5), working performance is very stable, light vibration. Jaw crusher cannot
The three types of crushers most commonly used for crushing CDW materials are the jaw crusher, the impact crusher and the gyratory crusher (Figure 4.4). A jaw crusher consists of two plates, with one oscillating back and forth against the other at a fixed angle ( Figure 4.4(a) ) and it is the most widely used in primary crushing stages ( Behera et al., 2014 ).
The jaw crushers and the gyratory crusher all employ a predominantly compressive force. Other coarse crushers Friable materials, such as coal, may be broken up without the application of large forces, and therefore less robust plant may be used.
all about jaw crusher and gyratory crusher . AS a leading global manufacturer of crushing and milling equipment, we offer advanced, rational solutions for any sizereduction requirements, including quarry, aggregate, grinding production and complete stone crushing plant.
Since the gyratory, unlike the jaw crusher, crushes on full cycle, it has a higher capacity than a jaw crusher of the same gape, roughly by a factor of 2.53, and is usually favored in plants handling large throughputs: in mines with crushing rates above 900 t h 1, gyratory crushers are always selected.
The gyratory crusher is mainly used for coarse crushing various hard materials as primary crusher. But it is not suitable for crushing viscous materials. General the largescale dressing mill uses gyratory crusher. Jaw crusher can crush high moisture, viscous ore, and not easily blocked.
