Product Description
China high chrome abrasion resistant blow bars are indispensable crusher spare parts and key wear-resistant castings, acting as core working components for VSI crushers and impact crushers. Crafted from premium high-chrome alloy (25-27% Cr content) with molybdenum and nickel additions, they deliver exceptional toughness and superior abrasion resistance to withstand high-frequency impacts and harsh wear in material crushing. Backed by China’s mature alloy smelting industrial chain and strict multi-stage quality inspections, they offer unbeatable cost-performance while meeting ISO and CE international standards.
Structurally optimized for maximum material contact, they boost crushing efficiency and ensure uniform particle size. Treated with advanced quenching-tempering and surface strengthening processes, these components reach HRC 58-63 hardness, extending service life by 50-100% vs. conventional parts and cutting replacement/maintenance costs. Widely used in mining, construction, and aggregate processing, they support stable, cost-effective operations for global crusher users.
Function and operation
✅ Impact and fracture: Blow bars strike the material entering the crusher, throwing it against an impact wall. This force causes the material to fracture into smaller particles.
✅ Rotor insertion: Multiple blow bars, typically in sets of three or four, are attached to the crusher's rotor.
✅ High-speed rotation: As the rotor spins at high speeds, the blow bars repeatedly impact the material until it is crushed to the desired size.
