Blow bars
Blow bars are precision-cast wear parts designed for impact crushers. Our blow bars are engineered to withstand extreme impact forces while maintaining consistent performance throughout their service life.
High chrome alloy
Formulated for high abrasion resistance and standard to heavy impact crushing operations.
Superior hardness (60-65 HRC), ideal for secondary and tertiary crushing of limestone and gravel.
High chrome with ceramic inserts
Reinforced composite matrix embedding high-strength ceramic grains at wear zones.
Extends service life up to 100%–200% in highly abrasive feed conditions and abrasive river stone.
