Read MoreDouble-toggle jaw crushers. In a double-toggle jaw crusher, the moving crusher jaw is driven by the eccentric shaft that moves the front and rear toggles up and down. Each shaft revolution causes the moving crusher jaw to close at the downstroke and open up during the upstroke. The toggle is kept in place by spring-loaded tension rod.

2 天之前 Cone crushers and jaw crushers both work by compression, reducing materials by squeezing them until they break apart. The benefit that cone crushers offer over jaw crushers is their ability to output a more cubical product similar to impact crushers. Cone crushers have traditionally been used as secondary and sometimes tertiary crushing ...

This leads to the use of gyratory crushers for large size crusher feed. When idling, gyratory crushers use up only about 30 % of the full load energy, whereas for jaw crushers the figure amounts to 45-50 %. In gyratory crushers lamellar or needle-shaped product is almost absent. On the other hand the wear of liners is higher than that of jaw ...
