There are many models of jaw crushers in the world. However, the jaw crushers can be divided into a single elbow crusher and elbows crusher from the structure of the jaw crusher. Nearly half a century, many factories have made the modern technology, such as a variety of senior roller bearings, hydraulic technology, non-blocking type of crushing chamber and high-strength materials apply to the structural improvements of the jaw crusher, which has obtained satisfactory process.

The single elbow crusher is also known as the compound pendulum jaw crusher or elevated eccentric shaft crusher. The mobile jaw directly hangs on the eccentric shaft and the low end of the mobile jaw is supported by a toggle plate (thrust plate). The other end of the toggle plate is directly supported by the posterior wall of the rack of the toggle plate bed. The mobile jaw rotates from the counter-clockwise direction. The upper stroke of the mobile jaw of single elbow crusher is large. Therefore, the production capacity of single elbow crusher is 30% more than that of the elbows crusher. In addition, the mobile jaw directly hangs on the eccentric shaft, which saves the rod of the eccentric axis. As a result, the weight is light and the footprint is small. The power consumption also reduces, but the wear of the liner of the single elbow crusher is more serious than that of elbows crusher. 

The elbows crusher is also known as simple pendulum jaw crusher or Blake crusher. The work is strong since the horizontal stroke of the most distant suspension point is large. In this way, the hard ore can be crushed. The vertical stroke of the mobile jaw is small and the wear of the liner of the elbows crusher is lighter than that of single elbow crusher. However, the upper stroke of the mobile jaw of the elbows crusher is small which affects its efficiency.
