Product Description
Martensitic blow bars are high-performance wear-resistant components engineered specifically for horizontal shaft impact (HSI) crushers, excelling in mining, quarrying, and construction waste recycling applications. Designed to handle tough materials—from hard rock (granite, iron ore) and limestone in mining to concrete debris, brick masonry, and recycled aggregates in construction recycling—they strike the perfect balance between hardness (44-57 HRC) and impact resistance (100-300 J/cm²). Unlike brittle high-chrome alternatives prone to breakage or less durable manganese steel, martensitic steel avoids fracture risks while outperforming manganese in abrasion resistance by up to 60%.
For mining operations, these blow bars tackle large feed sizes (up to 1000mm) and abrasive ores, ensuring consistent secondary/tertiary crushing productivity with minimal downtime. In construction recycling, they efficiently process mixed waste—including reinforced concrete and asphalt—meeting global standards for recycled aggregate quality. The advanced martensitic microstructure, refined via precision heat treatment, and ceramic-inserted variants (extending service life by 150%-200%) further reduce maintenance costs and material waste.
Compatible with leading crusher brands like Metso, Sandvik, and Terex, these versatile parts support both fixed and mobile crushing systems—critical for remote mining sites and on-site construction waste processing.
