Product Details
Material Differences
B2 Grinding Rods: Low-silicon alloy grinding rods
Applications: Fine grinding in rod mills
Low silicon content, high hardness, primarily wear-resistant, moderate impact resistance.
Suitable for sand and gravel aggregates, quartz sand, limestone, secondary fine grinding in cement plants, small rod mills, production lines with small feed particle sizes and low impact loads.
B3 Grinding Rods: High-silicon alloy grinding rods
Applications: Coarse grinding in rod mills, large feed, heavy-duty conditions
Higher silicon content, better toughness, impact resistance, less prone to breakage, wear resistance slightly lower than B2.
Suitable for metal ores, granite, hard ores, large material feed, rod mills with high impact.
Simple Selection: Hard materials, many large pieces > B3; Finer materials, low wear > B2.
Ore grinding media, long cylindrical steel rods, diameter 30-160mm, length 1.5-6m, most common in mining and sand and gravel industries.

Application areas
Steel is widely used in steel‑structure industrial buildings, bridge frameworks, the main structural systems of high‑rise buildings, and infrastructure projects such as highways and oil and gas pipelines. Its high strength ensures structural load‑bearing stability and seismic performance. In shipbuilding, steel is employed to fabricate hull structures, decks, and internal components. Hot‑rolled coil, with its excellent load‑carrying capacity, can withstand harsh operating conditions.
