Impact Crusher Wear Parts
Blow Bars
Primary wear components engineered for high-velocity impact crushing
Overview
Blow bars take the brunt of the impact in horizontal and vertical shaft impact crushers. Depending on your feed abrasiveness and impact severity, we advise on and cast blow bars in high-chromium white iron or manganese steel, balanced for smooth rotor operation.
Key Features
- Alloy selected to your feed's impact/abrasion mix
- Reversible designs to double usable wear life
- Balanced casting reduces rotor vibration
- Custom sizing for major HSI/VSI models
Typical Applications
Horizontal shaft impact (HSI) crushersVertical shaft impact (VSI) crushersLimestone, cement & aggregate crushing
