A stone jaw crusher is a primary crushing machine used in rock and mineral processing. It utilizes compressive force to break down large rocks into smaller, manageable pieces. Here’s a detailed overview:
Key Features of a Stone Jaw Crusher:
1. Robust Construction
– Made of high-quality materials (e.g., manganese steel) for durability.
– Fixed and movable jaw plates apply pressure to crush rocks.
2. Working Principle
– The motor drives the eccentric shaft, causing the movable jaw to move back and forth.
– Rocks are crushed between the fixed and moving jaws.
3. Applications
– Primary crushing in mining, quarrying, and construction.
– Suitable for hard rocks like granite, basalt, and river stone.
4. Advantages
– High efficiency & low maintenance.
– Adjustable discharge size for different output requirements.
– Simple structure & reliable operation.
5. Common Types
– Single-toggle jaw crusher: More compact with a circular motion for efficient crushing.
– Double-toggle jaw crusher: Stronger but more complex, ideal for tougher materials.
