The choice of material for jaw crusher plates depends on factors such as the type of material being crushed, the level of abrasiveness, and the crusher's intended application. Some common materials used for jaw plates include:
Unlike trading companies, MP Mining Machinery operates its own foundry and machining facility covering over 42,000 m². From raw material inspection to heat treatment and final testing, all jaw plates are produced in-house, ensuring consistent quality, stable delivery, and technical traceability.

One-Stop Logistics
Full export support with Door-to-Door (DDP/DDU) options to the USA, Australia, South Africa, and Canada.
Traceability
Every shipment includes a full technical dossier: Material Certificate, Heat Treatment Curve, and PT/UT Inspection Reports.
When designing the jaw plate, the peaks and valleys of the movable jaw and the fixed jaw should be opposite to ensure that, in addition to exerting a corresponding squeezing force on the material when the jaw plate is working, it can also exert a certain bending stress, which can effectively improve the crushing capacity.
For small and medium-sized jaw crushers, in order to extend the service life of the jaw plate, the jaw plate can be designed into a symmetrical shape so that it can turn around when the lower part is severely worn.
For large jaw crushers, the jaw plates can be designed into several symmetrical pieces to facilitate the replacement of worn blocks and extend the service life of the jaw plates.
When choosing jaw plate material, ZGMn13 can be used as the main material of the jaw plate. This type of manganese steel has strong toughness. Although its hardness is reduced, it has the characteristics of cold work hardening. During the working process of the jaw crusher, the extrusion force endured by the jaw plate causes it to be continuously squeezed and hardened during the working process. It wears and hardens until the wear exceeds the service limit and is scrapped. In addition, other factors such as cost must be considered when selecting materials.
The assembly of the jaw plate has a great influence on its service life. When assembling the jaw plate, it is necessary to firmly fix the jaw plate on the movable and fixed jaws, and use copper sheets, lead, zinc, etc. to maintain the same parallelism between the movable and fixed jaws. In order to avoid relative sliding between the jaw plate and the movable and fixed jaws when the jaw crusher is working, causing the jaw plate to wear or break, thereby reducing the service life of the jaw plate of the jaw crusher.
During the working process of the jaw crusher, the material is in direct contact with the jaw plate, and the jaw plate bears huge crushing force, especially for some materials with higher hardness. Strong force will cause the mounting bolts of the jaw plate to vibrate and loosen, thereby aggravating the wear of the jaw plate and even falling off or breaking.
Q: What material is best for jaw plates?
A: High manganese steel (Mn18 or Mn22) is most commonly used due to its work-hardening property under impact.
Q: How long do jaw plates last?
A: Service life depends on material hardness and feed size, but MP Mining jaw plates typically last 20–40% longer than standard grades.
Q: Can you produce jaw plates according to drawings or samples?
A: Yes, MP Mining supports OEM and custom jaw plates based on drawings, worn samples, or crusher model data.
Q: When to choose high manganese steel jaw plate?
A: For large jaw crushers, the crushed material is huge blocks, which forces the jaw plate to accept strong impact and wear. For that situation, the high manganese steel can give full play to the advantages of good toughness and hardness.
Q: What bearing is used in a jaw crusher?
A: Jaw crushers typically utilize spherical roller bearings, chosen for their ability to manage high radial loads and the presence of misalignment. Spherical roller bearings self-align and thus better compensate for shaft deflections and seat misalignment.
Q: Why do MP Mining jaw plates last longer?
A: It's the combination of our Step-Heating heat treatment and controlled water quenching. This ensures the manganese is "tough but not brittle," preventing cracks while providing high wear resistance.
Q: Do you provide the bolts and accessories?
A: Yes, we provide a one-stop solution including jaw wedges, cheek plates, bolts, and nuts.
