Product Details

Operating Process of rock jaw crusher machine:

1. In the process of large stones crushing into the small ones, the first step of crusher is called primary crusher.
2. The jaw crusher is of the most common use and hardest one.
3. The materials are fed into the crushing cavity from the top, forced to the cavity wall by the jaw tooth driven by the eccentric shaft throughout the frame, and crushed into smaller stones.
4. The eccentric movement is normally made by the fly wheels fixed on the both ends of the shaft. The roller bearings in support of the flywheels and eccentricity must bear the large impact load, abrasive sewage, and high temperature.
5. In spite of that, the jaw crusher can work reliably, which is the key link for guaranteeing the production efficiency.
