Core Advantages of Jaw Crusher Lining Products
● High-quality materials: Manufactured using special hard manganese steels (with manganese content ranging from 12% to 24%) and alloys—including high-wear-resistant materials such as Mn13Cr2, Mn18Cr2, and Mn22Cr2—these products have undergone independent verification and demonstrate outstanding performance in mining and aggregate production.
● Optimized design:
○ The liner plates of the jaw crusher and the jaw plates (fixed jaw plate and swing jaw plate) have been mechanically optimized in shape, significantly reducing wear.
○ A wide crushing cavity with a flat transition structure ensures smooth material feed, preventing accumulation and blockage at the top.
○ Side-wide channel design for easy maintenance and enhanced anti-blocking performance.
● Customized services: We offer single-piece, fully rotating, or standard two-piece liners to fit all OEM-brand jaw crushers.
Product Classification and Applicable Scenarios for Jaw Crusher Replacement Parts
1. Jaw Crusher Tooth Plate Series:
○ Activity鄂板: Accompany the dynamic crushing of the moving jaw plate.
○ Fixed jaw plate: Ensure the fixed jaw plate is securely supported.
2. Guide to Selecting Tooth Profiles for Jaw Crusher Lining Plates:
○ Medium-tooth: Ideal for crushing medium-hard rocks (such as gravel and aggregates), offering a balance between gripping force and wear resistance.
○ Cutting teeth: Specifically designed for hard rock, with deep tooth grooves that extend service life under high-abrasion conditions.
○ Multi-tooth crusher jaw plate: Specifically designed for the recycling industry, featuring a smooth surface plus a multi-tooth structure, effectively handling reinforced concrete mixtures.
○ Standard jaw crusher toggle plate: Suitable for soft rock or mixed materials; pay attention to model compatibility.
○ Heavy-duty fixed liner plates (square-tooth jaw crusher cheek plates): Designed for use with coarse teeth/medium teeth, reducing replacement frequency.
Material Selection for Rock Crusher Parts
● High-manganese steel: Highly impact-resistant, with a manganese content of 12%-24%, suitable for high-intensity crushing.
● Titanium carbide inlaid lining plate: The special casting process enhances crack resistance, resulting in a longer service life compared to conventional manganese steel.
Operating Principle and Maintenance Recommendations
● Working principle of the jaw crusher:
Through the coordinated motion of the fixed jaw plate and the moving jaw plate (driven by eccentricity), the material is crushed by compression within the crushing chamber. The moving jaw performs small-amplitude reciprocating impacts, gradually completing the crushing process.
● Key maintenance:
○ Regularly replace the jaw crusher liners to extend the equipment’s service life.
○ Select appropriate lining plates based on the feed material type (hard rock UCS > 160 MPa / soft rock UCS < 160 MPa, talc, etc.).
