The Working Principle Of A Jaw Crusher - Editors Top

Dec 25, 2014· The working principle of the jaw crushers is very simple. Powered by a diesel or gas motor, the jaw crusher brakes materials in a crushing chamber. The materials are pushed inside the chamber from the top opening and when crushed they are released through the bottom opening. The crushing power of the jaw crushers depends on the size of the chamber.

C series jaw crushers Wear parts application guide

In crushers like C105 and C3055, the jaw die design on the ends is different. The lock-ing wedges on these crushers are located behind the jaw dies rather than at the top of the jaw die. Jaw dies can be allowed to wear until the thickness is 60 to 65 mm thick, or the teeth are worn flat. On other crushers the ends of the jaw dies are much thinner.
