Cone crushers and gyratory crushers are mainly used as secondary crushers in a crushing plant. Crushed product from the primary crusher (usually Jaw Crusher) is fed through the top of the cone crusher and flows over the mantle. A vertical drive shaft rotates the mantle eccentrically below the bowl liner, squeezing the product and crushing it
Gyratory crushers are principally used in surfacecrushing plants. The gyratory crusher (Figure 6.5) consists essentially of a long spindle, carrying a hard steel conical grinding element, the head, seated in an eccentric sleeve.The spindle is suspended from a spider and, as it rotates, normally between 85 and 150 rpm, it sweeps out a conical path within the fixed crushing chamber, or
QS332 is the latest upgrade to our 2 Series product offering. Designed for versatility and ease of operation the QS332 offers a compact, high quality, secondary cone crushing solution. Fitted with CS430 "S" type gyratory cone crusher, it is capable of accepting large feed sizes whilst achieving high levels of production.
2020518&ensp·&enspWhile the Secondary and the Tertiary crushers travels between 500600 R.P.M. This difference in the speed results in a HAMMERING type crushing action over the SQUEEZING type employed by the primary. The other most noticeable change is the crushing action of the mantle. In the Gyratory all the movement is in the bottom of the crusher mantle
The gape of the secondary crusher should be 1.1 times larger than the largest particle in the feed and the feed should have 80% less than 70% of the feed opening of the crusher. Reference to manufacturers data on performance of cone crusher sizes is useful. Table 5.7 indicates the performance of cone crushers operating in open circuit. The

2020518&ensp·&enspEssentially, the gyratory crusher consists of a heavy castiron, or steel, frame which includes in its lower part an actuating mechanism (eccentric and driving gears), and in its upper part a coneshaped crushing chamber, lined with wearresisting plates (concaves).Spanning the crushing chamber across its top is a steadyrest (spider), containing a machined journal which fixes the position of
2020422&ensp·&enspA cone crusher is similar in operation to a gyratory crusher, with less steepness in the crushing chamber and more of a parallel zone between crushing zones. A cone crusher breaks rock by squeezing the rock between an eccentrically gyrating spindle, which is covered by a wearresistant mantle, and the enclosing concave hopper, covered by a
