Key wear-resistant elements for underground mining tools
Our Coal Mining Inserts are built for underground mining tools that must withstand continuous abrasion, localized crushing, and cyclic impact. Based on WC-Co carbide grades, these inserts are used in shearer picks, roadheader tools, continuous miner cutters, and related mining equipment.
Coal Mining Inserts are key cemented carbide wear-resistant working elements in coal machine picks, tunneling tools, and roadway construction equipment.
Manufacturing & Quality Control
Coal mining inserts are manufactured through controlled raw material preparation, wet mixing, pressing, vacuum sintering, optional densification, and precision finishing.
- Matching grain size and cobalt content with high-impact conditions
- Tooth tip profile, end transition, and assembly dimensional consistency
- Control of cracks, edge chipping, abnormal grains, and porosity
- Surface quality control for welding or press-fitting sections
Selection Recommendations
Choose the right insert for your conditions:
- **Pure coal seams with low abrasion**: use higher hardness grades to improve wear life
- **Coal-rock mixed layers with impact**: prioritize higher toughness and gradual tooth tip transition
- **Welded cutter heads**: verify welding process window and heat-affected zone risks
