Gyratory Crusher Liners
Gyratory crusher liners are heavy-duty wear components installed in primary gyratory crushers to protect the crushing chamber and ensure efficient fragmentation of large and abrasive rock materials. These liners include mantle and concave segments that work together under extreme compressive forces. In the Mining Industry, Cement Industry, and large-scale mineral processing plants, gyratory crusher liners directly affect throughput stability, energy efficiency, and downstream Grinding Circuit performance. BMB supplies engineered gyratory crusher liners designed for high Abrasion Resistance and long service life, serving industrial operations across Turkey, Iraq, Eurasia, and Europe.
Product Overview
Gyratory crusher liners consist of mantle and concave components that form the crushing chamber of a gyratory crusher. The mantle is the moving crushing surface, while concaves remain fixed, creating a high-pressure crushing zone for large ore size reduction.
These liners are essential crusher wear parts that determine crushing efficiency, product size distribution, and machine stability. In modern Grinding Circuit systems, gyratory crushers act as the first stage of size reduction feeding downstream Ball Mill and SAG Mill operations.
BMB designs liner systems with optimized geometry and metallurgical composition to ensure stable performance in high-load mining and cement applications.

Manufacturing Process
Every gyratory crusher liner BMB supplies is produced to our specification using controlled metallurgical and precision casting processes:
- Selection of high-grade manganese and alloy steels
- Electric furnace melting with strict chemical control
- Precision casting of mantle and concave geometry
- Heat treatment for hardness-toughness optimization
- CNC machining for dimensional accuracy
- Final inspection including hardness, crack detection, and geometry verification
This process ensures stable performance in continuous Grinding Circuit operations and minimizes unplanned shutdowns in industrial plants.
