Wave Ball Mill Cylinder Liner High Manganese Steel Shell Liner Long Life

Product Introduction

Wave ball mill cylinder liner is a core wear-resistant spare part installed on the inner wall of ball mill shell. Its wave-shaped profile is specially designed to lift and carry grinding media (steel balls) to a higher dropping point, producing stronger impact and cascading action, which significantly improves grinding efficiency and throughput while reducing power consumption.

As a sacrificial protective layer, the wave liner protects the mill cylinder from direct impact and abrasion by ore and steel balls, preventing shell deformation and extending mill service life. The wave profile is most suitable for coarse grinding and primary grinding in mineral processing plants.

We supply wave cylinder liners in high manganese steel (ZGMn13, ZGMn13Cr2, ZGMn18Cr2), high chrome cast iron and alloy cast steel. Custom casting is supported according to customer drawings, including wave height, pitch, thickness, bolt hole layout and single piece weight. Liners are compatible with both overflow and grate ball mills.

Key Advantages

• Wave profile lifts grinding media effectively, improves impact grinding efficiency
• High manganese steel impact-hardening property, excellent toughness for heavy impact
• Custom wave dimensions per drawing, precise fit for easy installation
• Long service life, reduces mill shutdown and replacement frequency
• OEM & ODM for copper, iron and gold ore grinding systems

Inspection Procedure

1. Raw Material Inspection Check chemical composition of molten steel by spectrometer. Verify alloy elements content to meet casting standard. Reject unqualified raw material before pouring.
2. Casting Visual Inspection Visual check for surface defects: sand hole, shrinkage, crack, slag inclusion. Clean casting riser and burrs. Mark defective pieces for rework or scrap.
3. Heat Treatment Inspection Monitor heat treatment temperature & holding time. Random sampling for hardness test (Brinell / HRC) to guarantee mechanical performance.
   
4. Dimension & Weight Inspection Measure overall size, thickness, bolt hole position and diameter. Compare with customer drawing. Check single piece weight, record deviation.
   
5. Non-Destructive Testing (NDT)

• MT Magnetic Particle Testing: Detect surface & near-surface cracks
  
• UT Ultrasonic Testing: Check internal shrinkage, porosity and inclusions NDT reports can be issued upon client request.
  

6.Final Sampling Inspection Random recheck of appearance, dimension and hardness. Compile full inspection documents including chemical report, hardness record and NDT certificate.

7.Packing Inspection Check seaworthy packing, mark part number, quantity and shipping mark before loading.

Application: Copper mine, iron ore mine, gold mine, mineral processing plant, cement plant. Suitable for overflow ball mill and grate ball mill, especially primary & coarse grinding circuits.
