What does a compound pendulum jaw crusher?

A compound pendulum jaw crusher is a type of device that is used in the mining and construction industries to crush rocks and other solid materials. It operates using two jaw plates, one of which is stationary while the other is movable. The movable jaw creates an elliptical motion as it swings around a pivot point at the top, crushing the material against the stationary plate.

Key features and benefits include:

1. High Crushing Efficiency: The elliptical motion allows for better crushing efficiency and effective force distribution.
2. Adjustable Output: The discharge opening can be adjusted to control the size of the output material.
3. Durability: Constructed with robust materials, it can handle significant wear and tear.
4. Versatility: Suitable for various types of materials, including very hard and abrasive ones.

It’s widely used for primary crushing in stone processing and aggregates production due to its ability to handle large feed sizes and produce uniform output.
