What Is a Jaw Crusher? Here's How It Works
Jaw crushers typically use the principles of compression and friction to break materials down. They're extremely powerful equipment that should be used with the utmost care. Jaw crushers are so powerful that they've earned the moniker "rock breakers" because of their brute force. All jaw crushers will have one fixed jaw and a moving one.

6. • Jaw Crusher • Jaw crusher is a type of crusher which produces coarse particle. • Feed size of the jaw crusher is 1500mm-40mm and the product size is from 50mm-5mm. • Compressive strength of jaw crushers is 320 mega Pascal. • Rpm for jaw crusher is between 200- 400. 7.
How Does a Jaw Crusher Work | Jaw Crusher | Kemper Equipment
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 ...
