jaw crusher and gyratory crusher

Jaw Crusher:

• Design: A jaw crusher consists of a fixed jaw and a movable jaw, with the movable jaw pivoting around a fixed hinge point. The jaws are designed to create a V-shaped cavity where the materials are fed into and crushed.
• Working Principle: The movable jaw exerts force on the rock by pressing it against the fixed jaw, crushing the material against the stationary jaw.
• Applications: Jaw crushers are commonly used for primary crushing of various materials, including hard rock, ores, and recycled concrete. They are suitable for both coarse and medium crushing applications.

Gyratory Crusher:

• Design: A gyratory crusher consists of a conical-shaped shell, typically lined with manganese steel, and a central vertical shaft with a concave surface and a mantle on top. The materials are fed into the crusher through the top opening and crushed between the mantle and concave.
• Working Principle: Gyratory crushers operate on the principle of compression, where the materials are crushed by the gyrating motion of the mantle against the concave surface. The crushing action is achieved by a gyrating movement of the main shaft eccentrically mounted on the central vertical shaft.
• Applications: Gyratory crushers are primarily used for primary crushing of large-sized materials, including hard rock and ores. They are commonly used in the mining industry and have a higher capacity than jaw crushers.

Differences:

• Design: Jaw crushers have a fixed jaw and a movable jaw, while gyratory crushers have a conical-shaped shell and a central vertical shaft.
• Crushing Principle: Jaw crushers crush materials by pressing them against the fixed jaw, whereas gyratory crushers crush materials by the gyrating motion of the mantle against the concave surface.
• Capacity: Gyratory crushers generally have a higher capacity than jaw crushers due to their larger size and design.
• Maintenance: Jaw crushers are easier to maintain and less costly to repair than gyratory crushers. Gyratory crushers have more complex maintenance requirements and are generally more expensive to maintain.

Both jaw crushers and gyratory crushers have their own advantages and are suitable for different applications. The selection between the two depends on factors such as the feed size, required capacity, desired product size, and cost considerations. It’s important to consider these factors and consult with experts to determine the most suitable crusher for a specific application.
