What is Crusher Jaw Plates?
A crusher jaw plate protects and supports the jaw crusher. A jaw plate is the most frequently changed wear part, so ensuring a quality graded jaw crusher is crucial. Jaw plates, also called ‘jaw dies, ‘ are often made of a mixture of graded composite or high-resistance steel.
Working Principles
Usually, in a conventional crushing operation, there are two jaw plates of moveable and stationary jaws. These jaws are located on the opposite sides of the crushing chambers. To fully segment and fracture the material, the moveable jaw plate works reciprocally to press the material against the fixed plate. The material continues to be crushed on the fixed jaw until refined enough to get through the jaw gap.

- Customizable Tooth Profile Design
We tailor tooth shape, tooth height and size according to customers’ raw material, feeding size and production demands, lifting crushing efficiency and extending service life.
- Ultra Wear-resistant TiC Composite Solution
Titanium Carbide embedded jaw plates are available for heavy-duty hard rock mining. Compared with ordinary manganese jaw plates, their service life is 3–5 times longer, effectively cutting frequent replacement downtime. This product has stable market feedback in Europe, Australia and Africa.
- One-stop Supporting Parts Service
Apart from jaw liners, we also supply side cheek plates, wedges, toggle plates, bolts and matching hardware, realizing full-set jaw crusher wear parts procurement for clients.
2.Manganese Jaw plate
Manganese Jaw Liner, Jaw plate exhibits distinct performance characteristics and application scopes.the manganese content increases (from MN13Cr2 to MN22Cr2), the overall strength and wear resistance
- MN13Cr2:Applicability: Suitable for jaw liner subjected to moderate load requirements, particularly in cost-sensitive industrial applications.Application Scope: Commonly used in medium-wear levels of jaw crushers, ideal for scenarios requiring high wearing with moderate demands on durability and strength.
- MN18Cr2:Performance Attributes: Offers enhanced wear resistance and strength compared to MN13Cr2.Applicability: Appropriate for jaw plate in moderate to high overload conditions, suitable for industries requiring increased durability and load-bearing capacity.
- MN22Cr2:Performance Attributes: Features the highest wear resistance and strength among the three grades, designed for extreme overload scenarios.Application Scope: Primarily used in high-wear environments such as mining equipment or industrial applications with high abrasive loading requirements. Ideal for scenarios needing exceptional wear resistance and impact resistance.
3.Titanium Carbide (TiC) Jaw Plates
Product Concept: TiC-embedded jaw plates utilize advanced composite technology to significantly extend wear part service life in high-load crushing applications. By dispersing titanium carbide particles within the base metal matrix, these plates deliver superior performance in demanding mining and aggregate operations.
