METSO Citic PXZ 50-65 1270mm x 1000 mm 600 HP Gyratory Crusher 1800-2600 TPH

A gyrator crusher (or gyratory crusher) is a heavy-duty piece of mining equipment used for primary crushing in large-scale mining operations. It is designed to handle large volumes of material and reduce ore or rock to a manageable size for further processing.

Key Features of a Gyratory Crusher:

1. Working Principle:
   • A gyratory crusher consists of a stationary outer shell (the concave) and a conical inner crushing head that gyrates within the concave.
   • As the crushing head oscillates, material is compressed and crushed between the two surfaces.
   • This action allows for continuous crushing, unlike some crushers that operate intermittently.
2. Capacity:
   • Gyratory crushers can process a vast amount of material and are particularly suited for use in high-capacity operations, such as large open-pit or underground mining projects.
3. Input Material:
   • They are used to crush hard, abrasive materials such as granite, basalt, and other types of rocks typically extracted in mining.
4. Adjustability:
   • Gyratory crushers allow for the adjustment of the discharge setting, enabling control over the size of the output material.
5. Advantages:
   • High capacity.
   • Efficient continuous operation.
   • Capability to handle very large feed sizes.
   • High reduction ratios (typically 6:1 to 8:1 or higher).

Applications in Mining:

• Primary Crusher: Gyratory crushers are often used as the primary crusher in mining operations, where they reduce large rocks or ore into smaller pieces suitable for secondary crushers or direct milling.
• Open-Pit Mining: Due to their capacity, they are commonly used in large-scale operations where substantial throughput is required.
• Underground Mining: In some cases, gyratory crushers are installed underground to save transport costs and improve efficiency.

Maintenance Considerations:

• Wear Parts: The concave and mantle are wear components that require periodic replacement.
• Lubrication: Effective lubrication systems are essential to ensure smooth operation and longevity.
• Regular Inspections: Gyratory crushers are complex machines that require routine maintenance and inspection to prevent breakdowns.

Gyratory crushers are integral to mining and industrial operations that process raw materials for various applications, including aggregate production and mineral extraction.
