Jaw Plate
Jaw plate is a fundamental wear component used in jaw crushers to form the crushing surface responsible for breaking hard and abrasive rock under high compressive force. The jaw plate directly determines crushing efficiency, energy consumption, and equipment lifetime in primary crushing systems. In the Mining Industry, Cement Industry, and aggregate production plants, jaw plate performance strongly affects downstream Grinding Circuit stability and feed quality for Ball Mill and SAG Mill systems. BMB supplies engineered jaw plates designed for high Wear Resistance and Abrasion Resistance, serving industrial operations across Turkey, Iraq, Eurasia, and Europe.
Product Overview
Jaw plates are installed on both fixed and movable jaws inside jaw crushers, forming the main crushing chamber. They apply compressive force to break large rocks into smaller sizes while protecting the crusher structure from direct wear.
The jaw plate plays a critical role in controlling crushing geometry, reduction ratio, and feed consistency. In modern Grinding Circuit systems, jaw plates ensure stable feed size for downstream Ball Mill and SAG Mill operations.
BMB designs jaw plates with optimized metallurgical composition and geometry to ensure stable performance under continuous high-impact and abrasive conditions.

Manufacturing Process
Every jaw plate BMB supplies is produced to our specification using controlled metallurgical and industrial processes:
- Selection of high-grade manganese and alloy steels
- Electric furnace melting with chemical composition control
- Precision sand casting or forging depending on application
- Heat treatment for hardness-toughness optimization
- CNC machining for dimensional accuracy
- Final inspection including hardness testing and crack detection
This ensures stable performance in Grinding Circuit operations and reduces unplanned downtime in industrial crushing plants.
