Fixed Jaw Plates | Movable Jaw Plates

Jaw Plates or Jaw Dies are the most frequently replaced wear parts of the jaw crusher, so the quality of the jaw die is one of the most important factors that determine the crushing efficiency and operating time.

A set of jaw plates are composed of the movable (swing jaw) and fixed jaw plate (stationary jaw). Compression of material undergoing crushing in a jaw crusher is achieved when the movable jaw die presses the feed against the fixed jaw die. The rock remains in the jaw of the crushing machine until it is small enough to pass through the gap towards the bottom of the jaws.





    Jaw plate is the main wear part of jaw crusher, which is divided into moving jaw plate and fixed jaw plate Hongfei’s jaw plate and cheek plate is manufactured with high manganese steel of Manganese 13%-30% to meet all kinds of requirement from clients.

    Through the special heat-treatment process, our jaw plate has stronger wear-resistant and the service life 10% longer than those made of traditional high manganese steel. According to the feedback from customers, the good performance of our jaw plate in different working condition greatly decreased the time of repair and the use-cost, and help client Improving comprehensive economic benefits.

    High Manganese Steel Jaw Plates

    Both stationary and movable jaw die could be flat surfaced or corrugated. In general, jaw plates are made of high manganese steel which is the dominant wear material. High manganese steel is also known as Hadfield manganese steel, a steel whose manganese content is very high and which possesses austenitic properties. Such plates are not only extremely tough but are also quite ductile and work-harden with use.

    We offer jaw plates in 13%, 18% and 22% grades of manganese with chromium ranging from 2%-3%. Check below table of our high manganese jaw die properties:
