The jaw crusher is one of the most widely used devices in the field of mining crushing. According to the differences in their structural features and working principles, there are mainly simple swing jaw crushers and compound swing jaw crushers.
Simple swing jaw crusher
1, Principle: The movable jaw is suspended on an eccentric shaft and performs a simple arc-shaped swing.
2, Features: It has a large crushing depth, and the material stays in the crushing chamber for a long time, which is prone to overcrushing (generating excessive fine materials), and has a relatively high energy consumption.
3, Application: It is mostly used in medium and small-sized mines or coarse crushing operations where the particle size requirements for the product are not high.
Compound swing jaw crusher
1, Principle: The movable jaw is not only suspended on the eccentric shaft but also connected to the connecting rod at the bottom, performing complex planar movements (including both horizontal extrusion and vertical up and down movements).
2, Features
High efficiency: The vertical component force helps the material to be discharged downward, accelerating the crushing rhythm.
Low wear: The upper horizontal stroke of the movable jaw is large (conducive to coarse crushing), and the lower vertical stroke is large (conducive to material discharge), and the wear of the liner is relatively uniform.
3, Application: Currently the mainstream model in the market, it is widely used for coarse and medium crushing of various ores.
