Jaw Plates – High-Manganese Steel Jaw Crusher Wear Parts for Mining and Aggregate Crushing
Q1: What are jaw plates used for?
Πλάκες γνάθου, also known as jaw dies or tooth plates, are the core wearable parts of jaw crushers. They directly contact the material, withstanding tremendous compressive and grinding forces. Their performance and quality directly determine the operational efficiency and maintenance costs of the crusher.
Q2: What are the key specifications of jaw plates?
Jaw plates are available in various sizes to match different jaw crusher models, ranging from small PE-150×250 to large PE-900×1200 and larger. Common materials include Mn13, Mn18, Mn13Cr2, and Mn18Cr2 high-manganese steel. Custom sizes and tooth patterns are available upon request.
What This Product Is Built For
Jaw plates are high-performance wearable parts engineered for jaw crushers in mining, λατομεία, and aggregate processing operations. The plates are available in two configurations: fixed jaw plates installed on the crusher frame, and movable jaw plates mounted on the reciprocating jaw. As the movable jaw periodically approaches and retreats from the fixed jaw, the material is crushed through compression. The plates feature high-manganese steel construction that work-hardens under impact, developing a hard, wear-resistant surface while maintaining tough, ductile interior properties.

Why YNJ Jaw Plates Stand Out
Premium High-Manganese Steel Construction
Manufactured from premium Mn13, Mn18, Mn13Cr2, and Mn18Cr2 high-manganese steel, the jaw plates deliver exceptional wear resistance and long service life. The work-hardening characteristic ensures the surface becomes harder under impact while maintaining a tough, crack-resistant core.
Superior Casting and Heat Treatment Processes
Advanced casting technologies including V-process, EPC (lost foam), and water glass sand casting, combined with water toughening heat treatment, ensure the plates achieve optimal hardness, tensile strength, and toughness for demanding crushing applications.
Precision Fit for Major Crusher Brands
Available in sizes to match all major jaw crusher models including PE, PEX, and international brands. Custom manufacturing is available for non-standard or specialized requirements.
Long Service Life for Cost Savings
Extended wear life reduces the frequency of replacement, minimizing downtime and lowering overall operating costs for mining and aggregate operations.
Multiple Tooth Pattern Options
Available in various tooth patterns including regular teeth (RT-BITE), flat teeth (FT-BITE), and sharp teeth (ST-BITE) to suit different material types and crushing requirements.
Jaw Plates: Buyer Watchpoints
Select the Right Material for Your Application
For highly abrasive materials (granite, basalt, quartz), Mn18 or Mn13Cr2 high-manganese steel is recommended. For medium-abrasive materials (limestone, iron ore), Mn13 is typically sufficient. For low-abrasive or recycled materials, standard tooth patterns may be adequate.
Match Specifications to Your Crusher Model
Jaw plates must match the exact crusher model and specifications. Buyers should verify the model number and measure existing plates before ordering. Custom sizes are available for non-standard applications.
Consider Tooth Pattern for Optimal Performance
Different tooth patterns are designed for different material types. Regular teeth are suitable for general applications, flat teeth for finer crushing, and sharp teeth for harder materials. Consulting with technical experts can help optimize selection.
Monitor Wear and Maintain Spare Stock
Jaw plates should be replaced when tooth height is worn beyond 2/3 of the original height or when cracking or deformation occurs. Maintaining a spare set on hand reduces costly downtime.
