1. Definition and Structure
The jaw crusher (also known as jaw crusher, tiger mouth) is a mechanical device with a crushing chamber composed of two jaw plates, the movable jaw and the static jaw, which completes the extrusion and crushing of materials by simulating the periodic movement of the two jaws of animals. Its core components include the frame, eccentric shaft, movable jaw plate, fixed jaw plate, toggle plate, flywheel and gap adjustment screw, etc. The crushing chamber adopts a trapezoidal design with a large upper part and a small lower part, in which the toggle plate also has a safety function.
2. Working Principle
The jaw crusher is driven by a motor-driven pulley to drive the eccentric shaft to rotate, so that the movable jaw periodically approaches or moves away from the fixed jaw. When the movable jaw rises, the material is squeezed, crushed and crushed between the two jaws; when the movable jaw descends, the crushed material is discharged by its own weight. Continuous crushing operation is achieved. The deep-cavity jaw crusher can improve the processing capacity (10-100 tons/hour) and reduce energy consumption by optimizing the cavity design.The jaw crusher is driven by a motor-driven pulley to drive the eccentric shaft to rotate, so that the movable jaw periodically approaches or moves away from the fixed jaw.

3. Performance characteristics of jaw crusher
1. High crushing efficiency
Adopting the principle of flexural extrusion crushing, the crushing ratio can reach 4-6, and the finished product particle size is uniform.
2. Reliable and durable structure
The high manganese steel jaw plate and high-strength frame design can handle hard materials with compressive strength ≤320MPa (such as iron ore, basalt)
3. Flexible adjustment and low operation and maintenance cost
The gasket-type discharge port adjustment device supports rapid particle size adjustment, and the integrated design of the lubrication system is easy to maintain.
4. Environmental optimization
The fully sealed structure reduces dust leakage, and the new shock absorption technology reduces operating noise.
