Although there are differences between jaw crusher and other types of stone crusher , they have the same designed purpose: crush stones. Generally, jaw crusher can be regarded as a primary crusher machinery. In order to meet different requirements, jaw crusher can be portable or stationary.
Generally, when the jaw crusher is used as a stationary machine, it has higher production but can't be transported from location to location. On the contrary, when it is used as a portable machine, it can be moved easily but product fewer crushed materials.
Jaw crusher can be used to help dispose the construction trash. Jaw crusher crushes trash into smaller pieces and the small-size trash is easier to load and dump. When some large materials need to be transported to another place, you'd better break down the materials into small pieces first and remove the small-size materials easily and safely.
The difference between the overhead eccentric jaw crusher and the double-toggle jaw crusher is the location of the pivot point. The pivot of the former is at the bottom while the pivot of the latter is at the top. The metal wall of the crushing chamber is connected with the pivot point and guided by a rotating. Generally, the latter is more popular for low-cost energy and easy-use method.
While you are choosing to buy a jaw crusher, consider your needs and find the most suitable one. As usual, you should pay attention to the size of the crushing chamber opening, the size should be large enough to feed into materials to crush. Another aspect you should consider is the length of the crushing chamber. The longer it is, the more power it has. So if you want to crush extremely hard material, you'd better choose the jaw crusher with a long crushing chamber.
