PAJOA Blow Bars with Patented Alloys for Impact Crushers

Blow bars are thick metal plates mounted on the outer edge of the rotor. They are the primary wear parts responsible for breaking down materials such as concrete, limestone, granite, and construction debris. Installed in sets of three or four, blow bars play a decisive role in crushing efficiency, product sizing, and machine longevity.

Pajoa offers blow bars in a range of materials to match different working conditions. Options include high manganese steel for excellent toughness, martensitic steel for balanced wear and impact resistance, high chromium alloy for superior hardness, and composite solutions with ceramic inserts or bi-metal structures for extreme abrasion or high-impact environments.
