High Manganese Steel Sag Mill Liner and Ball Mill Grate Plates for Mining Machinery

High Manganese Steel Sag Mill Liner and Ball Mill Grate Plates for Mining Machinery

Product Description
We specialize in manufacturing premium wear-resistant castings for mining machinery, focusing on liners and grates for Ball Mills, Jaw Crushers, and SAG/AG Mills. Our factory produces castings in High Manganese Steel, High Chrome, Alloy Steel, and Ductile Iron to suit various working conditions.

Applications

• SAG/AG Mill Liners: Heavy-duty castings ensuring maximum uptime under severe grinding conditions and impact forces from large ore feed .

• Ball Mill Liners / Grate Plates: Designed for low impact and high abrasion resistance, utilizing High Chrome or Alloy Steel to extend service life.

• Jaw Crusher Plates: Manufactured from High Manganese Steel to withstand high impact loading, featuring work-hardening properties for self-protection.

Production and Quality Inspection
Our commitment to quality is verified through a rigorous multi-stage inspection process.

1. Chemical Composition Analysis: We strictly control the content of Cr, Mn, Mo, and Ni to ensure the material meets the specification for the specific working condition.

2. Heat Treatment: Every casting undergoes precise thermal processing to achieve the desired metallurgical structure and eliminate internal stress.

   • 

3. 3D Scanning: Advanced 3D scanning is used to verify the geometric accuracy of the casting against the original CAD design.

   • 

4. Hardness Testing: We perform Rockwell or Brinell hardness tests to confirm the wear-resistant properties (e.g., High Chrome ≥ HRC60).

   • 

5. Non-Destructive Testing (NDT): To guarantee the structural integrity of the parts:

   • MT (Magnetic Particle Testing): To detect surface cracks.

   • UT (Ultrasonic Testing): To detect internal shrinkage or porosity.

   • 

6. Dimensional Inspection: We use precision measuring tools to ensure the liners fit perfectly during installation.

   • 

7. Metallographic Analysis: We examine the microstructure to ensure proper carbide formation and pearlite/martensite distribution.
