Abrasion-resistant liner drum cover rubber

Case 1: Coal mine conveyor system modification (Wear-resistant liner+Roller Covering)

Project Background: The original conveyor system of a large coal mine had serious wear and tear on the chute and drum, leading to frequent downtime for replacement and affecting production efficiency.
prescription::

• Wear-resistant liner: Adoption 16Mn high hardness steel plate + ceramic compositelinerCritical Wear Area Inlayaluminum oxideCeramic block (thickness 10mm).
• Roller Covering: The drive and idler pulleys are made of Cold Vulcanization Overmolding(nitrile rubber(15mm thickness, herringbone non-slip design).
  effect::
  ✔ Chute life from 3 months raise to More than 2 years
  ✔ Rubberized pulleys reduce belt slippage and lower wear rates 60%
  ✔ Decrease in annual maintenance costs 40%

Case 2:clinkerPlant raw material conveying line (ceramic wear-resistant liner)

concern: Raw cement (with quartz sand) wears out metal liners very quickly, requiring replacement in an average of 1 month.
Improvement program::

• Laying in chutes and guide chutes Ceramic-Rubber Composite Liner(Al₂O₃ ceramics, anti-sticking on pockmarked surfaces).
• The roller is made of High temperature resistant polyurethane overmolding(Temperature-resistant 120°C, diamond pattern)
  results-based::
  ✔ Lining life Extended to 18 months
  ✔ Reduced raw material adhesion 50%The frequency of clean-ups has been significantly reduced

Case 3:PortIron ore loading and unloading system (super wear-resistant drum cover)

challenge: High abrasion of iron ore powder + humid environment, resulting in rapid peeling of the drum rubber surface.
programmatic::

• platen Hot Vulcanized OvermoldingAdoption Highly abrasion-resistant synthetic rubber(Containssilicon carbide(granules, hardness Shore 85°).
• combining Ceramic Liner Protecting the impact zone of the falling material.
  effect::
  ✔ Gel-covered life from 6 months raise to 3 years
  ✔ Belt deflection problems reduced 70%

Summary of key lessons learned

1. Wear-resistant liner selection::
   • High-impact conditions(e.g.mines) → Select Metal based liners (high chrome cast iron/65Mn)
   • Fine particle wear(e.g. cement, coal) → selection Ceramic composite liner
2. Roller Covering Essentials::
   • humid environment → Nitrile rubber (hydrolysis resistant)
   • High temperature materials → polyurethane or heat-resistant rubber (≤180°C)
   • Anti-slip requirements → Herringbone/rhombus pattern design
