Tungsten Carbide Studs
HPGR and crusher wear protection
حالة المخزونMade to drawing
مدة التوريد4 - 8 weeks depending on pattern and quantity
Wear-resistant tungsten carbide studs for HPGR and demanding mining and mineral processing applications. Supplied to your roller drawing or stud pattern, with grade selection matched to the ore abrasiveness and the duty — from fine-grain high-hardness grades for abrasive quartzite feeds to tougher binder grades where impact and edge loading dominate.
- Grade selected against ore abrasiveness, moisture and impact level
- Supplied to your roller drawing and stud pattern
- Consistent press-fit tolerance for reliable interference in the roller bore
- Batch certification with hardness and density records
