Essential Components for Efficient Crushing: Jaw Crusher Plates

The jaw is a crucial part of the jaw crusher, consisting of two main components: the movable jaw plate and the fixed jaw plate. These two plates form the working chamber of the crusher, where materials are subjected to significant crushing forces and friction. Due to the intense wear and tear 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 long - term operation of the crusher.

The surface of the crushing plates is generally designed with teeth, which play a vital role in the crushing process. The peak angle of these teeth usually ranges from 90° to 120°, depending on the characteristics of the material being crushed. For larger bulk materials, a larger angle is more appropriate, while smaller materials require a smaller angle. The pitch of the teeth is generally determined by the desired size of the final product and is often set to be approximately equal to the width of the discharge port. For optimal performance, the ratio of tooth height to pitch is preferably maintained between 0.5 and 0.33.

During operation, the wear on the crushing plates is uneven. The lower part of the plate wears out more rapidly than the upper part because of the direct contact with materials and the higher crushing forces in that area. Since the crushing plates are in direct contact with the materials, their service life is directly related to the efficiency and production costs of the jaw crusher. Therefore, extending the lifespan of these plates is essential for maintaining operational efficiency and minimizing downtime.

To enhance the durability and performance of jaw crusher plates, multiple factors need to be considered, including design optimization, material selection, assembly accuracy, and improvements in the usage process. LulanPanda specializes in supplying high - quality jaw crusher plates made from ultra - high manganese steel and other advanced materials. Through strict scientific procedures such as smelting, casting, and heat treatment, we ensure that our plates have excellent wear resistance and a longer service life.

Our jaw crusher plates are available in a wide range of models and types to meet different crushing needs. We use manganese steel grades like Mn18 and Mn21, which have a manganese content of over 13%, ensuring excellent wear resistance and durability. Moreover, our work - hardening technology enables the plates to increase in hardness under pressure, further enhancing their performance. The heat - treatment process we adopt, known as "tough water treatment," ensures that the plates maintain good 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 ideal solution for your jaw crusher requirements. Don't hesitate to contact us with your specific needs, and we will promptly offer customized recommendations to meet your operational demands.
