Jaw Crusher Plates: Essential Components for Efficient Crushing
The jaw is a critical component of the jaw crusher, consisting of two main parts: the movable jaw plate and the fixed jaw plate. These plates form the working chamber of the crusher, where materials are subjected to immense crushing forces and friction. Due to the intense wear and tear experienced during operation, both the movable and fixed jaw plates are typically equipped with wear liners, commonly referred to as crushing plates or jaw plates. These liners are designed to protect the jaw structure and ensure the longevity of the crusher.
The surface of the crushing plates is usually designed with teeth, which play a vital role in the crushing process. The peak angle of these teeth typically ranges between 90° and 120°, depending on the nature of the material being processed. For larger bulk materials, a greater angle is preferred, while smaller materials require a smaller angle. The pitch of the teeth is generally determined by the desired product size and is often set to be approximately equal to the width of the discharge port. The ratio of tooth height to pitch is ideally maintained between 0.5 and 0.33 for optimal performance.
During operation, the wear on the crushing plates is not uniform. The lower section of the plate tends to wear out faster than the upper section due to the direct contact with materials and the higher crushing forces exerted in that area. Since the crushing plates are in direct contact with the materials, their lifespan is directly tied to the efficiency and production costs of the jaw crusher. Therefore, extending the life of these plates is crucial for maintaining operational efficiency and reducing downtime.
To enhance the durability and performance of jaw crusher plates, several factors must be considered, including design optimization, material selection, assembly precision, and improvements in the usage process. Our company specializes in providing high-quality jaw crusher plates made from ultra-high manganese steel and other advanced materials. Through rigorous scientific processes such as smelting, casting, and heat treatment, we ensure that our plates exhibit exceptional wear resistance and extended service life.
Our jaw crusher plates are available in various models and types to suit different crushing requirements. We utilize manganese steel grades such as Mn18 and Mn21, which contain over 13% manganese content, ensuring superior wear resistance and durability. Additionally, our work hardening technology allows the plates to increase in hardness under pressure, further enhancing their performance. The heat treatment process we employ, known as "tough water treatment," ensures that the plates maintain excellent toughness and avoid performance degradation caused by natural phase transitions.
With our advanced manufacturing techniques and commitment to quality, we are confident in providing the perfect solution for your jaw crusher needs. Feel free to contact us with your specific requirements, and we will promptly offer tailored recommendations to meet your operational demands.
